Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569622, here are decompositions:

5 + 31569617 = 31569622
23 + 31569599 = 31569622
41 + 31569581 = 31569622
53 + 31569569 = 31569622
131 + 31569491 = 31569622
173 + 31569449 = 31569622
263 + 31569359 = 31569622
389 + 31569233 = 31569622

Showing the first eight; more decompositions exist.
