Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568008, here are decompositions:

47 + 31567961 = 31568008
149 + 31567859 = 31568008
239 + 31567769 = 31568008
359 + 31567649 = 31568008
389 + 31567619 = 31568008
449 + 31567559 = 31568008
557 + 31567451 = 31568008
1097 + 31566911 = 31568008

Showing the first eight; more decompositions exist.
