Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604982, here are decompositions:

23 + 31604959 = 31604982
179 + 31604803 = 31604982
193 + 31604789 = 31604982
223 + 31604759 = 31604982
239 + 31604743 = 31604982
251 + 31604731 = 31604982
263 + 31604719 = 31604982
293 + 31604689 = 31604982

Showing the first eight; more decompositions exist.
