Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612710, here are decompositions:

43 + 31612667 = 31612710
47 + 31612663 = 31612710
83 + 31612627 = 31612710
89 + 31612621 = 31612710
113 + 31612597 = 31612710
127 + 31612583 = 31612710
137 + 31612573 = 31612710
163 + 31612547 = 31612710

Showing the first eight; more decompositions exist.
