Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476612, here are decompositions:

5 + 31476607 = 31476612
19 + 31476593 = 31476612
61 + 31476551 = 31476612
103 + 31476509 = 31476612
113 + 31476499 = 31476612
151 + 31476461 = 31476612
163 + 31476449 = 31476612
179 + 31476433 = 31476612

Showing the first eight; more decompositions exist.
