Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604104, here are decompositions:

5 + 31604099 = 31604104
47 + 31604057 = 31604104
53 + 31604051 = 31604104
71 + 31604033 = 31604104
113 + 31603991 = 31604104
173 + 31603931 = 31604104
227 + 31603877 = 31604104
347 + 31603757 = 31604104

Showing the first eight; more decompositions exist.
