Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599824, here are decompositions:

13 + 31599811 = 31599824
43 + 31599781 = 31599824
97 + 31599727 = 31599824
271 + 31599553 = 31599824
337 + 31599487 = 31599824
577 + 31599247 = 31599824
631 + 31599193 = 31599824
877 + 31598947 = 31599824

Showing the first eight; more decompositions exist.
