Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568076, here are decompositions:

5 + 31568071 = 31568076
17 + 31568059 = 31568076
193 + 31567883 = 31568076
227 + 31567849 = 31568076
257 + 31567819 = 31568076
263 + 31567813 = 31568076
307 + 31567769 = 31568076
347 + 31567729 = 31568076

Showing the first eight; more decompositions exist.
