Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612366, here are decompositions:

3 + 31612363 = 31612366
53 + 31612313 = 31612366
59 + 31612307 = 31612366
89 + 31612277 = 31612366
167 + 31612199 = 31612366
257 + 31612109 = 31612366
353 + 31612013 = 31612366
449 + 31611917 = 31612366

Showing the first eight; more decompositions exist.
