Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607528, here are decompositions:

67 + 31607461 = 31607528
79 + 31607449 = 31607528
229 + 31607299 = 31607528
571 + 31606957 = 31607528
577 + 31606951 = 31607528
787 + 31606741 = 31607528
877 + 31606651 = 31607528
991 + 31606537 = 31607528

Showing the first eight; more decompositions exist.
