Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569708, here are decompositions:

7 + 31569701 = 31569708
17 + 31569691 = 31569708
19 + 31569689 = 31569708
61 + 31569647 = 31569708
67 + 31569641 = 31569708
109 + 31569599 = 31569708
127 + 31569581 = 31569708
139 + 31569569 = 31569708

Showing the first eight; more decompositions exist.
