Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607000, here are decompositions:

3 + 31606997 = 31607000
37 + 31606963 = 31607000
43 + 31606957 = 31607000
97 + 31606903 = 31607000
349 + 31606651 = 31607000
421 + 31606579 = 31607000
457 + 31606543 = 31607000
463 + 31606537 = 31607000

Showing the first eight; more decompositions exist.
