Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463944, here are decompositions:

3 + 31463941 = 31463944
23 + 31463921 = 31463944
47 + 31463897 = 31463944
53 + 31463891 = 31463944
101 + 31463843 = 31463944
137 + 31463807 = 31463944
227 + 31463717 = 31463944
263 + 31463681 = 31463944

Showing the first eight; more decompositions exist.
