Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509696, here are decompositions:

5 + 31509691 = 31509696
13 + 31509683 = 31509696
37 + 31509659 = 31509696
67 + 31509629 = 31509696
79 + 31509617 = 31509696
103 + 31509593 = 31509696
139 + 31509557 = 31509696
167 + 31509529 = 31509696

Showing the first eight; more decompositions exist.
