Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604292, here are decompositions:

11 + 31604281 = 31604292
29 + 31604263 = 31604292
73 + 31604219 = 31604292
101 + 31604191 = 31604292
103 + 31604189 = 31604292
163 + 31604129 = 31604292
193 + 31604099 = 31604292
241 + 31604051 = 31604292

Showing the first eight; more decompositions exist.
