Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599718, here are decompositions:

11 + 31599707 = 31599718
47 + 31599671 = 31599718
89 + 31599629 = 31599718
107 + 31599611 = 31599718
167 + 31599551 = 31599718
617 + 31599101 = 31599718
659 + 31599059 = 31599718
809 + 31598909 = 31599718

Showing the first eight; more decompositions exist.
