Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574764, here are decompositions:

17 + 31574747 = 31574764
41 + 31574723 = 31574764
71 + 31574693 = 31574764
83 + 31574681 = 31574764
107 + 31574657 = 31574764
233 + 31574531 = 31574764
257 + 31574507 = 31574764
311 + 31574453 = 31574764

Showing the first eight; more decompositions exist.
