Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510496, here are decompositions:

7 + 31510489 = 31510496
37 + 31510459 = 31510496
97 + 31510399 = 31510496
109 + 31510387 = 31510496
487 + 31510009 = 31510496
547 + 31509949 = 31510496
607 + 31509889 = 31510496
613 + 31509883 = 31510496

Showing the first eight; more decompositions exist.
