Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463938, here are decompositions:

17 + 31463921 = 31463938
29 + 31463909 = 31463938
41 + 31463897 = 31463938
47 + 31463891 = 31463938
59 + 31463879 = 31463938
89 + 31463849 = 31463938
131 + 31463807 = 31463938
179 + 31463759 = 31463938

Showing the first eight; more decompositions exist.
