Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612170, here are decompositions:

19 + 31612151 = 31612170
61 + 31612109 = 31612170
89 + 31612081 = 31612170
101 + 31612069 = 31612170
127 + 31612043 = 31612170
157 + 31612013 = 31612170
173 + 31611997 = 31612170
229 + 31611941 = 31612170

Showing the first eight; more decompositions exist.
