Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567710, here are decompositions:

11 + 31567699 = 31567710
17 + 31567693 = 31567710
23 + 31567687 = 31567710
29 + 31567681 = 31567710
37 + 31567673 = 31567710
61 + 31567649 = 31567710
67 + 31567643 = 31567710
73 + 31567637 = 31567710

Showing the first eight; more decompositions exist.
