Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612464, here are decompositions:

11 + 31612453 = 31612464
41 + 31612423 = 31612464
73 + 31612391 = 31612464
83 + 31612381 = 31612464
101 + 31612363 = 31612464
113 + 31612351 = 31612464
151 + 31612313 = 31612464
157 + 31612307 = 31612464

Showing the first eight; more decompositions exist.
