Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598050, here are decompositions:

17 + 31598033 = 31598050
23 + 31598027 = 31598050
41 + 31598009 = 31598050
53 + 31597997 = 31598050
89 + 31597961 = 31598050
137 + 31597913 = 31598050
173 + 31597877 = 31598050
227 + 31597823 = 31598050

Showing the first eight; more decompositions exist.
