Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595008, here are decompositions:

17 + 31594991 = 31595008
47 + 31594961 = 31595008
89 + 31594919 = 31595008
101 + 31594907 = 31595008
131 + 31594877 = 31595008
197 + 31594811 = 31595008
239 + 31594769 = 31595008
251 + 31594757 = 31595008

Showing the first eight; more decompositions exist.
