Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612110, here are decompositions:

29 + 31612081 = 31612110
31 + 31612079 = 31612110
41 + 31612069 = 31612110
67 + 31612043 = 31612110
97 + 31612013 = 31612110
113 + 31611997 = 31612110
193 + 31611917 = 31612110
199 + 31611911 = 31612110

Showing the first eight; more decompositions exist.
