Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599008, here are decompositions:

19 + 31598989 = 31599008
61 + 31598947 = 31599008
97 + 31598911 = 31599008
151 + 31598857 = 31599008
229 + 31598779 = 31599008
307 + 31598701 = 31599008
487 + 31598521 = 31599008
607 + 31598401 = 31599008

Showing the first eight; more decompositions exist.
