Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612156, here are decompositions:

5 + 31612151 = 31612156
47 + 31612109 = 31612156
113 + 31612043 = 31612156
239 + 31611917 = 31612156
263 + 31611893 = 31612156
353 + 31611803 = 31612156
419 + 31611737 = 31612156
509 + 31611647 = 31612156

Showing the first eight; more decompositions exist.
