Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607708, here are decompositions:

19 + 31607689 = 31607708
37 + 31607671 = 31607708
79 + 31607629 = 31607708
109 + 31607599 = 31607708
127 + 31607581 = 31607708
157 + 31607551 = 31607708
367 + 31607341 = 31607708
409 + 31607299 = 31607708

Showing the first eight; more decompositions exist.
