Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511062, here are decompositions:

5 + 31511057 = 31511062
59 + 31511003 = 31511062
131 + 31510931 = 31511062
251 + 31510811 = 31511062
263 + 31510799 = 31511062
281 + 31510781 = 31511062
293 + 31510769 = 31511062
383 + 31510679 = 31511062

Showing the first eight; more decompositions exist.
