Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612716, here are decompositions:

53 + 31612663 = 31612716
89 + 31612627 = 31612716
97 + 31612619 = 31612716
127 + 31612589 = 31612716
229 + 31612487 = 31612716
263 + 31612453 = 31612716
293 + 31612423 = 31612716
347 + 31612369 = 31612716

Showing the first eight; more decompositions exist.
