Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595506, here are decompositions:

23 + 31595483 = 31595506
113 + 31595393 = 31595506
227 + 31595279 = 31595506
233 + 31595273 = 31595506
263 + 31595243 = 31595506
269 + 31595237 = 31595506
317 + 31595189 = 31595506
443 + 31595063 = 31595506

Showing the first eight; more decompositions exist.
