Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569922, here are decompositions:

71 + 31569851 = 31569922
233 + 31569689 = 31569922
281 + 31569641 = 31569922
353 + 31569569 = 31569922
431 + 31569491 = 31569922
443 + 31569479 = 31569922
563 + 31569359 = 31569922
641 + 31569281 = 31569922

Showing the first eight; more decompositions exist.
