Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598080, here are decompositions:

23 + 31598057 = 31598080
47 + 31598033 = 31598080
53 + 31598027 = 31598080
71 + 31598009 = 31598080
83 + 31597997 = 31598080
167 + 31597913 = 31598080
257 + 31597823 = 31598080
317 + 31597763 = 31598080

Showing the first eight; more decompositions exist.
