Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612086, here are decompositions:

5 + 31612081 = 31612086
7 + 31612079 = 31612086
17 + 31612069 = 31612086
43 + 31612043 = 31612086
73 + 31612013 = 31612086
89 + 31611997 = 31612086
179 + 31611907 = 31612086
193 + 31611893 = 31612086

Showing the first eight; more decompositions exist.
