Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599908, here are decompositions:

7 + 31599901 = 31599908
31 + 31599877 = 31599908
37 + 31599871 = 31599908
97 + 31599811 = 31599908
127 + 31599781 = 31599908
181 + 31599727 = 31599908
409 + 31599499 = 31599908
421 + 31599487 = 31599908

Showing the first eight; more decompositions exist.
