Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599798, here are decompositions:

17 + 31599781 = 31599798
31 + 31599767 = 31599798
37 + 31599761 = 31599798
71 + 31599727 = 31599798
127 + 31599671 = 31599798
149 + 31599649 = 31599798
199 + 31599599 = 31599798
311 + 31599487 = 31599798

Showing the first eight; more decompositions exist.
