Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604164, here are decompositions:

107 + 31604057 = 31604164
113 + 31604051 = 31604164
131 + 31604033 = 31604164
173 + 31603991 = 31604164
233 + 31603931 = 31604164
443 + 31603721 = 31604164
521 + 31603643 = 31604164
587 + 31603577 = 31604164

Showing the first eight; more decompositions exist.
