Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510294, here are decompositions:

71 + 31510223 = 31510294
107 + 31510187 = 31510294
173 + 31510121 = 31510294
293 + 31510001 = 31510294
353 + 31509941 = 31510294
401 + 31509893 = 31510294
443 + 31509851 = 31510294
503 + 31509791 = 31510294

Showing the first eight; more decompositions exist.
