Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612338, here are decompositions:

29 + 31612309 = 31612338
31 + 31612307 = 31612338
61 + 31612277 = 31612338
97 + 31612241 = 31612338
137 + 31612201 = 31612338
139 + 31612199 = 31612338
229 + 31612109 = 31612338
257 + 31612081 = 31612338

Showing the first eight; more decompositions exist.
