Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625892, here are decompositions:

43 + 31625849 = 31625892
71 + 31625821 = 31625892
73 + 31625819 = 31625892
113 + 31625779 = 31625892
131 + 31625761 = 31625892
139 + 31625753 = 31625892
211 + 31625681 = 31625892
239 + 31625653 = 31625892

Showing the first eight; more decompositions exist.
