Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599992, here are decompositions:

79 + 31599913 = 31599992
181 + 31599811 = 31599992
211 + 31599781 = 31599992
439 + 31599553 = 31599992
643 + 31599349 = 31599992
733 + 31599259 = 31599992
1039 + 31598953 = 31599992
1069 + 31598923 = 31599992

Showing the first eight; more decompositions exist.
