Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612574, here are decompositions:

43 + 31612531 = 31612574
61 + 31612513 = 31612574
151 + 31612423 = 31612574
193 + 31612381 = 31612574
211 + 31612363 = 31612574
223 + 31612351 = 31612574
373 + 31612201 = 31612574
577 + 31611997 = 31612574

Showing the first eight; more decompositions exist.
