Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595108, here are decompositions:

7 + 31595101 = 31595108
109 + 31594999 = 31595108
241 + 31594867 = 31595108
379 + 31594729 = 31595108
409 + 31594699 = 31595108
499 + 31594609 = 31595108
607 + 31594501 = 31595108
619 + 31594489 = 31595108

Showing the first eight; more decompositions exist.
