Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476464, here are decompositions:

3 + 31476461 = 31476464
7 + 31476457 = 31476464
13 + 31476451 = 31476464
31 + 31476433 = 31476464
73 + 31476391 = 31476464
181 + 31476283 = 31476464
277 + 31476187 = 31476464
307 + 31476157 = 31476464

Showing the first eight; more decompositions exist.
