Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604958, here are decompositions:

109 + 31604849 = 31604958
191 + 31604767 = 31604958
199 + 31604759 = 31604958
211 + 31604747 = 31604958
227 + 31604731 = 31604958
239 + 31604719 = 31604958
269 + 31604689 = 31604958
271 + 31604687 = 31604958

Showing the first eight; more decompositions exist.
