Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463986, here are decompositions:

23 + 31463963 = 31463986
89 + 31463897 = 31463986
107 + 31463879 = 31463986
137 + 31463849 = 31463986
179 + 31463807 = 31463986
227 + 31463759 = 31463986
269 + 31463717 = 31463986
467 + 31463519 = 31463986

Showing the first eight; more decompositions exist.
