Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612484, here are decompositions:

3 + 31612481 = 31612484
31 + 31612453 = 31612484
61 + 31612423 = 31612484
103 + 31612381 = 31612484
283 + 31612201 = 31612484
487 + 31611997 = 31612484
577 + 31611907 = 31612484
601 + 31611883 = 31612484

Showing the first eight; more decompositions exist.
