Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604962, here are decompositions:

3 + 31604959 = 31604962
29 + 31604933 = 31604962
113 + 31604849 = 31604962
173 + 31604789 = 31604962
239 + 31604723 = 31604962
281 + 31604681 = 31604962
353 + 31604609 = 31604962
359 + 31604603 = 31604962

Showing the first eight; more decompositions exist.
