Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599790, here are decompositions:

17 + 31599773 = 31599790
23 + 31599767 = 31599790
29 + 31599761 = 31599790
83 + 31599707 = 31599790
107 + 31599683 = 31599790
137 + 31599653 = 31599790
179 + 31599611 = 31599790
191 + 31599599 = 31599790

Showing the first eight; more decompositions exist.
