Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510644, here are decompositions:

13 + 31510631 = 31510644
17 + 31510627 = 31510644
41 + 31510603 = 31510644
71 + 31510573 = 31510644
83 + 31510561 = 31510644
103 + 31510541 = 31510644
127 + 31510517 = 31510644
157 + 31510487 = 31510644

Showing the first eight; more decompositions exist.
