Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510796, here are decompositions:

7 + 31510789 = 31510796
43 + 31510753 = 31510796
139 + 31510657 = 31510796
193 + 31510603 = 31510796
223 + 31510573 = 31510796
307 + 31510489 = 31510796
337 + 31510459 = 31510796
349 + 31510447 = 31510796

Showing the first eight; more decompositions exist.
