Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599998, here are decompositions:

97 + 31599901 = 31599998
127 + 31599871 = 31599998
139 + 31599859 = 31599998
271 + 31599727 = 31599998
349 + 31599649 = 31599998
499 + 31599499 = 31599998
691 + 31599307 = 31599998
739 + 31599259 = 31599998

Showing the first eight; more decompositions exist.
