Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463908, here are decompositions:

11 + 31463897 = 31463908
17 + 31463891 = 31463908
29 + 31463879 = 31463908
59 + 31463849 = 31463908
101 + 31463807 = 31463908
149 + 31463759 = 31463908
191 + 31463717 = 31463908
227 + 31463681 = 31463908

Showing the first eight; more decompositions exist.
