Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606796, here are decompositions:

43 + 31606753 = 31606796
139 + 31606657 = 31606796
367 + 31606429 = 31606796
373 + 31606423 = 31606796
409 + 31606387 = 31606796
457 + 31606339 = 31606796
499 + 31606297 = 31606796
709 + 31606087 = 31606796

Showing the first eight; more decompositions exist.
