Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612992, here are decompositions:

11 + 31612981 = 31612992
23 + 31612969 = 31612992
31 + 31612961 = 31612992
41 + 31612951 = 31612992
53 + 31612939 = 31612992
79 + 31612913 = 31612992
101 + 31612891 = 31612992
139 + 31612853 = 31612992

Showing the first eight; more decompositions exist.
