Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612176, here are decompositions:

67 + 31612109 = 31612176
97 + 31612079 = 31612176
107 + 31612069 = 31612176
163 + 31612013 = 31612176
179 + 31611997 = 31612176
269 + 31611907 = 31612176
283 + 31611893 = 31612176
293 + 31611883 = 31612176

Showing the first eight; more decompositions exist.
