Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569836, here are decompositions:

7 + 31569829 = 31569836
43 + 31569793 = 31569836
73 + 31569763 = 31569836
127 + 31569709 = 31569836
223 + 31569613 = 31569836
457 + 31569379 = 31569836
499 + 31569337 = 31569836
577 + 31569259 = 31569836

Showing the first eight; more decompositions exist.
