Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599968, here are decompositions:

67 + 31599901 = 31599968
97 + 31599871 = 31599968
109 + 31599859 = 31599968
157 + 31599811 = 31599968
241 + 31599727 = 31599968
619 + 31599349 = 31599968
661 + 31599307 = 31599968
709 + 31599259 = 31599968

Showing the first eight; more decompositions exist.
