Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612332, here are decompositions:

19 + 31612313 = 31612332
23 + 31612309 = 31612332
109 + 31612223 = 31612332
131 + 31612201 = 31612332
181 + 31612151 = 31612332
211 + 31612121 = 31612332
223 + 31612109 = 31612332
251 + 31612081 = 31612332

Showing the first eight; more decompositions exist.
