Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569074, here are decompositions:

37 + 31569037 = 31569074
157 + 31568917 = 31569074
223 + 31568851 = 31569074
241 + 31568833 = 31569074
307 + 31568767 = 31569074
331 + 31568743 = 31569074
337 + 31568737 = 31569074
373 + 31568701 = 31569074

Showing the first eight; more decompositions exist.
