Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463512, here are decompositions:

5 + 31463507 = 31463512
23 + 31463489 = 31463512
29 + 31463483 = 31463512
53 + 31463459 = 31463512
83 + 31463429 = 31463512
149 + 31463363 = 31463512
191 + 31463321 = 31463512
251 + 31463261 = 31463512

Showing the first eight; more decompositions exist.
