Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463932, here are decompositions:

11 + 31463921 = 31463932
23 + 31463909 = 31463932
41 + 31463891 = 31463932
53 + 31463879 = 31463932
83 + 31463849 = 31463932
89 + 31463843 = 31463932
173 + 31463759 = 31463932
251 + 31463681 = 31463932

Showing the first eight; more decompositions exist.
