Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509714, here are decompositions:

17 + 31509697 = 31509714
23 + 31509691 = 31509714
31 + 31509683 = 31509714
53 + 31509661 = 31509714
73 + 31509641 = 31509714
97 + 31509617 = 31509714
113 + 31509601 = 31509714
157 + 31509557 = 31509714

Showing the first eight; more decompositions exist.
