Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604956, here are decompositions:

23 + 31604933 = 31604956
107 + 31604849 = 31604956
167 + 31604789 = 31604956
197 + 31604759 = 31604956
233 + 31604723 = 31604956
269 + 31604687 = 31604956
347 + 31604609 = 31604956
353 + 31604603 = 31604956

Showing the first eight; more decompositions exist.
