Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612206, here are decompositions:

5 + 31612201 = 31612206
7 + 31612199 = 31612206
97 + 31612109 = 31612206
127 + 31612079 = 31612206
137 + 31612069 = 31612206
163 + 31612043 = 31612206
193 + 31612013 = 31612206
313 + 31611893 = 31612206

Showing the first eight; more decompositions exist.
