Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598074, here are decompositions:

17 + 31598057 = 31598074
41 + 31598033 = 31598074
47 + 31598027 = 31598074
113 + 31597961 = 31598074
197 + 31597877 = 31598074
251 + 31597823 = 31598074
281 + 31597793 = 31598074
311 + 31597763 = 31598074

Showing the first eight; more decompositions exist.
