Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612462, here are decompositions:

71 + 31612391 = 31612462
149 + 31612313 = 31612462
239 + 31612223 = 31612462
263 + 31612199 = 31612462
311 + 31612151 = 31612462
353 + 31612109 = 31612462
383 + 31612079 = 31612462
419 + 31612043 = 31612462

Showing the first eight; more decompositions exist.
