Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604950, here are decompositions:

17 + 31604933 = 31604950
101 + 31604849 = 31604950
191 + 31604759 = 31604950
227 + 31604723 = 31604950
263 + 31604687 = 31604950
269 + 31604681 = 31604950
347 + 31604603 = 31604950
389 + 31604561 = 31604950

Showing the first eight; more decompositions exist.
