Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612456, here are decompositions:

3 + 31612453 = 31612456
149 + 31612307 = 31612456
179 + 31612277 = 31612456
233 + 31612223 = 31612456
257 + 31612199 = 31612456
347 + 31612109 = 31612456
443 + 31612013 = 31612456
563 + 31611893 = 31612456

Showing the first eight; more decompositions exist.
