Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569774, here are decompositions:

7 + 31569767 = 31569774
11 + 31569763 = 31569774
13 + 31569761 = 31569774
23 + 31569751 = 31569774
37 + 31569737 = 31569774
73 + 31569701 = 31569774
83 + 31569691 = 31569774
127 + 31569647 = 31569774

Showing the first eight; more decompositions exist.
