Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510832, here are decompositions:

19 + 31510813 = 31510832
43 + 31510789 = 31510832
61 + 31510771 = 31510832
79 + 31510753 = 31510832
151 + 31510681 = 31510832
229 + 31510603 = 31510832
271 + 31510561 = 31510832
373 + 31510459 = 31510832

Showing the first eight; more decompositions exist.
