Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604202, here are decompositions:

11 + 31604191 = 31604202
13 + 31604189 = 31604202
73 + 31604129 = 31604202
103 + 31604099 = 31604202
151 + 31604051 = 31604202
211 + 31603991 = 31604202
269 + 31603933 = 31604202
271 + 31603931 = 31604202

Showing the first eight; more decompositions exist.
