Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569526, here are decompositions:

47 + 31569479 = 31569526
89 + 31569437 = 31569526
167 + 31569359 = 31569526
179 + 31569347 = 31569526
239 + 31569287 = 31569526
269 + 31569257 = 31569526
293 + 31569233 = 31569526
389 + 31569137 = 31569526

Showing the first eight; more decompositions exist.
