Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599902, here are decompositions:

31 + 31599871 = 31599902
43 + 31599859 = 31599902
79 + 31599823 = 31599902
199 + 31599703 = 31599902
349 + 31599553 = 31599902
463 + 31599439 = 31599902
643 + 31599259 = 31599902
709 + 31599193 = 31599902

Showing the first eight; more decompositions exist.
