Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173656, here are decompositions:

5 + 173651 = 173656
83 + 173573 = 173656
107 + 173549 = 173656
113 + 173543 = 173656
173 + 173483 = 173656
227 + 173429 = 173656
347 + 173309 = 173656
359 + 173297 = 173656

Showing the first eight; more decompositions exist.
