Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604130, here are decompositions:

31 + 31604099 = 31604130
73 + 31604057 = 31604130
79 + 31604051 = 31604130
97 + 31604033 = 31604130
139 + 31603991 = 31604130
197 + 31603933 = 31604130
199 + 31603931 = 31604130
211 + 31603919 = 31604130

Showing the first eight; more decompositions exist.
