Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56686, here are decompositions:

5 + 56681 = 56686
23 + 56663 = 56686
53 + 56633 = 56686
89 + 56597 = 56686
167 + 56519 = 56686
197 + 56489 = 56686
233 + 56453 = 56686
269 + 56417 = 56686

Showing the first eight; more decompositions exist.
