Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598020, here are decompositions:

11 + 31598009 = 31598020
23 + 31597997 = 31598020
59 + 31597961 = 31598020
107 + 31597913 = 31598020
197 + 31597823 = 31598020
227 + 31597793 = 31598020
257 + 31597763 = 31598020
281 + 31597739 = 31598020

Showing the first eight; more decompositions exist.
