Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179656, here are decompositions:

5 + 179651 = 179656
23 + 179633 = 179656
53 + 179603 = 179656
83 + 179573 = 179656
107 + 179549 = 179656
137 + 179519 = 179656
173 + 179483 = 179656
227 + 179429 = 179656

Showing the first eight; more decompositions exist.
