Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612976, here are decompositions:

7 + 31612969 = 31612976
37 + 31612939 = 31612976
103 + 31612873 = 31612976
223 + 31612753 = 31612976
229 + 31612747 = 31612976
313 + 31612663 = 31612976
349 + 31612627 = 31612976
379 + 31612597 = 31612976

Showing the first eight; more decompositions exist.
