Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569746, here are decompositions:

37 + 31569709 = 31569746
367 + 31569379 = 31569746
379 + 31569367 = 31569746
409 + 31569337 = 31569746
487 + 31569259 = 31569746
499 + 31569247 = 31569746
577 + 31569169 = 31569746
673 + 31569073 = 31569746

Showing the first eight; more decompositions exist.
