Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598188, here are decompositions:

47 + 31598141 = 31598188
131 + 31598057 = 31598188
179 + 31598009 = 31598188
191 + 31597997 = 31598188
227 + 31597961 = 31598188
311 + 31597877 = 31598188
449 + 31597739 = 31598188
467 + 31597721 = 31598188

Showing the first eight; more decompositions exist.
