Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463812, here are decompositions:

5 + 31463807 = 31463812
53 + 31463759 = 31463812
131 + 31463681 = 31463812
293 + 31463519 = 31463812
353 + 31463459 = 31463812
383 + 31463429 = 31463812
449 + 31463363 = 31463812
491 + 31463321 = 31463812

Showing the first eight; more decompositions exist.
