Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612384, here are decompositions:

3 + 31612381 = 31612384
71 + 31612313 = 31612384
107 + 31612277 = 31612384
233 + 31612151 = 31612384
263 + 31612121 = 31612384
443 + 31611941 = 31612384
467 + 31611917 = 31612384
491 + 31611893 = 31612384

Showing the first eight; more decompositions exist.
