Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42656, here are decompositions:

7 + 42649 = 42656
13 + 42643 = 42656
67 + 42589 = 42656
79 + 42577 = 42656
157 + 42499 = 42656
193 + 42463 = 42656
199 + 42457 = 42656
223 + 42433 = 42656

Showing the first eight; more decompositions exist.
