Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612150, here are decompositions:

29 + 31612121 = 31612150
41 + 31612109 = 31612150
71 + 31612079 = 31612150
107 + 31612043 = 31612150
137 + 31612013 = 31612150
233 + 31611917 = 31612150
239 + 31611911 = 31612150
257 + 31611893 = 31612150

Showing the first eight; more decompositions exist.
