Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598656, here are decompositions:

113 + 31598543 = 31598656
137 + 31598519 = 31598656
197 + 31598459 = 31598656
233 + 31598423 = 31598656
239 + 31598417 = 31598656
293 + 31598363 = 31598656
389 + 31598267 = 31598656
443 + 31598213 = 31598656

Showing the first eight; more decompositions exist.
