Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463914, here are decompositions:

3 + 31463911 = 31463914
5 + 31463909 = 31463914
17 + 31463897 = 31463914
23 + 31463891 = 31463914
71 + 31463843 = 31463914
107 + 31463807 = 31463914
197 + 31463717 = 31463914
233 + 31463681 = 31463914

Showing the first eight; more decompositions exist.
