Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569674, here are decompositions:

61 + 31569613 = 31569674
193 + 31569481 = 31569674
307 + 31569367 = 31569674
337 + 31569337 = 31569674
373 + 31569301 = 31569674
397 + 31569277 = 31569674
523 + 31569151 = 31569674
601 + 31569073 = 31569674

Showing the first eight; more decompositions exist.
