Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612446, here are decompositions:

17 + 31612429 = 31612446
23 + 31612423 = 31612446
83 + 31612363 = 31612446
137 + 31612309 = 31612446
139 + 31612307 = 31612446
223 + 31612223 = 31612446
337 + 31612109 = 31612446
367 + 31612079 = 31612446

Showing the first eight; more decompositions exist.
