Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569794, here are decompositions:

13 + 31569781 = 31569794
31 + 31569763 = 31569794
43 + 31569751 = 31569794
103 + 31569691 = 31569794
181 + 31569613 = 31569794
313 + 31569481 = 31569794
457 + 31569337 = 31569794
547 + 31569247 = 31569794

Showing the first eight; more decompositions exist.
