Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598008, here are decompositions:

11 + 31597997 = 31598008
47 + 31597961 = 31598008
131 + 31597877 = 31598008
269 + 31597739 = 31598008
311 + 31597697 = 31598008
467 + 31597541 = 31598008
641 + 31597367 = 31598008
809 + 31597199 = 31598008

Showing the first eight; more decompositions exist.
