Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612122, here are decompositions:

13 + 31612109 = 31612122
41 + 31612081 = 31612122
43 + 31612079 = 31612122
53 + 31612069 = 31612122
79 + 31612043 = 31612122
109 + 31612013 = 31612122
181 + 31611941 = 31612122
211 + 31611911 = 31612122

Showing the first eight; more decompositions exist.
