Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463712, here are decompositions:

23 + 31463689 = 31463712
31 + 31463681 = 31463712
179 + 31463533 = 31463712
193 + 31463519 = 31463712
223 + 31463489 = 31463712
229 + 31463483 = 31463712
283 + 31463429 = 31463712
349 + 31463363 = 31463712

Showing the first eight; more decompositions exist.
