Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612396, here are decompositions:

5 + 31612391 = 31612396
83 + 31612313 = 31612396
89 + 31612307 = 31612396
173 + 31612223 = 31612396
197 + 31612199 = 31612396
317 + 31612079 = 31612396
353 + 31612043 = 31612396
383 + 31612013 = 31612396

Showing the first eight; more decompositions exist.
