Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599906, here are decompositions:

5 + 31599901 = 31599906
29 + 31599877 = 31599906
47 + 31599859 = 31599906
83 + 31599823 = 31599906
97 + 31599809 = 31599906
139 + 31599767 = 31599906
179 + 31599727 = 31599906
199 + 31599707 = 31599906

Showing the first eight; more decompositions exist.
