Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598056, here are decompositions:

23 + 31598033 = 31598056
29 + 31598027 = 31598056
47 + 31598009 = 31598056
59 + 31597997 = 31598056
179 + 31597877 = 31598056
233 + 31597823 = 31598056
263 + 31597793 = 31598056
293 + 31597763 = 31598056

Showing the first eight; more decompositions exist.
