Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569696, here are decompositions:

5 + 31569691 = 31569696
7 + 31569689 = 31569696
79 + 31569617 = 31569696
83 + 31569613 = 31569696
97 + 31569599 = 31569696
127 + 31569569 = 31569696
317 + 31569379 = 31569696
337 + 31569359 = 31569696

Showing the first eight; more decompositions exist.
