Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463980, here are decompositions:

17 + 31463963 = 31463980
59 + 31463921 = 31463980
71 + 31463909 = 31463980
83 + 31463897 = 31463980
89 + 31463891 = 31463980
101 + 31463879 = 31463980
131 + 31463849 = 31463980
137 + 31463843 = 31463980

Showing the first eight; more decompositions exist.
