Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467810, here are decompositions:

43 + 31467767 = 31467810
47 + 31467763 = 31467810
83 + 31467727 = 31467810
89 + 31467721 = 31467810
163 + 31467647 = 31467810
223 + 31467587 = 31467810
239 + 31467571 = 31467810
251 + 31467559 = 31467810

Showing the first eight; more decompositions exist.
