Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569326, here are decompositions:

7 + 31569319 = 31569326
67 + 31569259 = 31569326
79 + 31569247 = 31569326
97 + 31569229 = 31569326
157 + 31569169 = 31569326
277 + 31569049 = 31569326
409 + 31568917 = 31569326
457 + 31568869 = 31569326

Showing the first eight; more decompositions exist.
