Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607006, here are decompositions:

43 + 31606963 = 31607006
103 + 31606903 = 31607006
127 + 31606879 = 31607006
349 + 31606657 = 31607006
463 + 31606543 = 31607006
577 + 31606429 = 31607006
619 + 31606387 = 31607006
709 + 31606297 = 31607006

Showing the first eight; more decompositions exist.
