Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615796, here are decompositions:

13 + 31615783 = 31615796
67 + 31615729 = 31615796
127 + 31615669 = 31615796
193 + 31615603 = 31615796
307 + 31615489 = 31615796
313 + 31615483 = 31615796
367 + 31615429 = 31615796
379 + 31615417 = 31615796

Showing the first eight; more decompositions exist.
