Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510698, here are decompositions:

7 + 31510691 = 31510698
17 + 31510681 = 31510698
19 + 31510679 = 31510698
41 + 31510657 = 31510698
67 + 31510631 = 31510698
71 + 31510627 = 31510698
137 + 31510561 = 31510698
157 + 31510541 = 31510698

Showing the first eight; more decompositions exist.
