Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505304, here are decompositions:

7 + 31505297 = 31505304
11 + 31505293 = 31505304
163 + 31505141 = 31505304
167 + 31505137 = 31505304
223 + 31505081 = 31505304
227 + 31505077 = 31505304
277 + 31505027 = 31505304
317 + 31504987 = 31505304

Showing the first eight; more decompositions exist.
