COMMENTS
Numbers n such that n+A003627(n)=A007645(n).
No more terms between 80 and 300000. The sequence is likely finite because the prime number race between the primes of the forms 3n+1 and 3n+2 (see the Granville-Martin link in A003627) reaches only differences of a few hundred while the indices in the two sequences are of the order of millions.

EXAMPLE
a(1)=1 because 1+A003627(1)=1+2=3+A007645(1); a(2)=2 because 2+A003627(2)=2+5=7=A007645(2); a(3)=38 because 38+A003627(38)=38+359=397=A007645(38); a(4)=80 because 80+A003627(80)=80+911=991=A007645(80).
