Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31304, here are decompositions:

37 + 31267 = 31304
67 + 31237 = 31304
73 + 31231 = 31304
127 + 31177 = 31304
151 + 31153 = 31304
157 + 31147 = 31304
181 + 31123 = 31304
223 + 31081 = 31304

Showing the first eight; more decompositions exist.
