 A071636 Numbers n=4*k+2 such that there is no pair of primes p and q of form 4*i+1 with p+q=n; A071635(n)=0. 1
 2, 6, 14, 38, 62 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS Conjecture: there are no more terms. LINKS EXAMPLE 62=4*15+2 is a term, as p = 3 modulo 4 for all primes p in decompositions of 62 into sum of two primes: 3+59=11+51=19+43=31+31; 66=4*16+2 is not a term, as e.g. 66=5+61=(4*1+1)+(4*15+1): A071635(16)>0. CROSSREFS Cf. A002144, A002145.
