Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465950, here are decompositions:

59 + 31465891 = 31465950
71 + 31465879 = 31465950
101 + 31465849 = 31465950
149 + 31465801 = 31465950
193 + 31465757 = 31465950
223 + 31465727 = 31465950
239 + 31465711 = 31465950
277 + 31465673 = 31465950

Showing the first eight; more decompositions exist.
