Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568002, here are decompositions:

3 + 31567999 = 31568002
41 + 31567961 = 31568002
71 + 31567931 = 31568002
233 + 31567769 = 31568002
293 + 31567709 = 31568002
353 + 31567649 = 31568002
359 + 31567643 = 31568002
383 + 31567619 = 31568002

Showing the first eight; more decompositions exist.
