Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598128, here are decompositions:

71 + 31598057 = 31598128
101 + 31598027 = 31598128
131 + 31597997 = 31598128
167 + 31597961 = 31598128
251 + 31597877 = 31598128
389 + 31597739 = 31598128
431 + 31597697 = 31598128
557 + 31597571 = 31598128

Showing the first eight; more decompositions exist.
