Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612524, here are decompositions:

11 + 31612513 = 31612524
37 + 31612487 = 31612524
43 + 31612481 = 31612524
71 + 31612453 = 31612524
101 + 31612423 = 31612524
173 + 31612351 = 31612524
211 + 31612313 = 31612524
283 + 31612241 = 31612524

Showing the first eight; more decompositions exist.
