Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612624, here are decompositions:

3 + 31612621 = 31612624
5 + 31612619 = 31612624
41 + 31612583 = 31612624
137 + 31612487 = 31612624
233 + 31612391 = 31612624
311 + 31612313 = 31612624
317 + 31612307 = 31612624
347 + 31612277 = 31612624

Showing the first eight; more decompositions exist.
