Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178654, here are decompositions:

11 + 178643 = 178654
41 + 178613 = 178654
53 + 178601 = 178654
83 + 178571 = 178654
167 + 178487 = 178654
173 + 178481 = 178654
251 + 178403 = 178654
257 + 178397 = 178654

Showing the first eight; more decompositions exist.
