Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510898, here are decompositions:

7 + 31510891 = 31510898
109 + 31510789 = 31510898
127 + 31510771 = 31510898
241 + 31510657 = 31510898
271 + 31510627 = 31510898
337 + 31510561 = 31510898
409 + 31510489 = 31510898
439 + 31510459 = 31510898

Showing the first eight; more decompositions exist.
