Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599512, here are decompositions:

13 + 31599499 = 31599512
73 + 31599439 = 31599512
163 + 31599349 = 31599512
199 + 31599313 = 31599512
409 + 31599103 = 31599512
523 + 31598989 = 31599512
601 + 31598911 = 31599512
673 + 31598839 = 31599512

Showing the first eight; more decompositions exist.
