Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104656, here are decompositions:

5 + 104651 = 104656
17 + 104639 = 104656
59 + 104597 = 104656
107 + 104549 = 104656
113 + 104543 = 104656
197 + 104459 = 104656
239 + 104417 = 104656
257 + 104399 = 104656

Showing the first eight; more decompositions exist.
