Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612294, here are decompositions:

17 + 31612277 = 31612294
53 + 31612241 = 31612294
71 + 31612223 = 31612294
173 + 31612121 = 31612294
251 + 31612043 = 31612294
281 + 31612013 = 31612294
353 + 31611941 = 31612294
383 + 31611911 = 31612294

Showing the first eight; more decompositions exist.
