Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612458, here are decompositions:

5 + 31612453 = 31612458
29 + 31612429 = 31612458
67 + 31612391 = 31612458
89 + 31612369 = 31612458
107 + 31612351 = 31612458
149 + 31612309 = 31612458
151 + 31612307 = 31612458
181 + 31612277 = 31612458

Showing the first eight; more decompositions exist.
