Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569974, here are decompositions:

31 + 31569943 = 31569974
181 + 31569793 = 31569974
193 + 31569781 = 31569974
211 + 31569763 = 31569974
223 + 31569751 = 31569974
283 + 31569691 = 31569974
607 + 31569367 = 31569974
673 + 31569301 = 31569974

Showing the first eight; more decompositions exist.
