%N Numbers that are the sum of 2 different primes, with repetitions.

%e 16=3+13=5+11 hence 16 occurs twice.

%e 24=5+19=7+13=11+13 hence 24 occurs 3 times.

%e 50=p+q with {p,q}={{3,47},{7,43},{13,37},{19,31}}, 4 representations.

%e 48=p+q with {p,q}={{5,43},{7,41},{11,37},{17,31},{19,29}}, 5 representations.
