Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612336, here are decompositions:

23 + 31612313 = 31612336
29 + 31612307 = 31612336
59 + 31612277 = 31612336
113 + 31612223 = 31612336
137 + 31612199 = 31612336
227 + 31612109 = 31612336
257 + 31612079 = 31612336
293 + 31612043 = 31612336

Showing the first eight; more decompositions exist.
