Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604916, here are decompositions:

53 + 31604863 = 31604916
67 + 31604849 = 31604916
113 + 31604803 = 31604916
127 + 31604789 = 31604916
149 + 31604767 = 31604916
157 + 31604759 = 31604916
173 + 31604743 = 31604916
193 + 31604723 = 31604916

Showing the first eight; more decompositions exist.
