Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612314, here are decompositions:

5 + 31612309 = 31612314
7 + 31612307 = 31612314
37 + 31612277 = 31612314
73 + 31612241 = 31612314
113 + 31612201 = 31612314
163 + 31612151 = 31612314
193 + 31612121 = 31612314
233 + 31612081 = 31612314

Showing the first eight; more decompositions exist.
