Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476512, here are decompositions:

3 + 31476509 = 31476512
13 + 31476499 = 31476512
61 + 31476451 = 31476512
79 + 31476433 = 31476512
139 + 31476373 = 31476512
163 + 31476349 = 31476512
229 + 31476283 = 31476512
439 + 31476073 = 31476512

Showing the first eight; more decompositions exist.
