Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11656, here are decompositions:

23 + 11633 = 11656
59 + 11597 = 11656
107 + 11549 = 11656
137 + 11519 = 11656
167 + 11489 = 11656
173 + 11483 = 11656
233 + 11423 = 11656
257 + 11399 = 11656

Showing the first eight; more decompositions exist.
