Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454306, here are decompositions:

43 + 31454263 = 31454306
109 + 31454197 = 31454306
157 + 31454149 = 31454306
223 + 31454083 = 31454306
229 + 31454077 = 31454306
283 + 31454023 = 31454306
313 + 31453993 = 31454306
337 + 31453969 = 31454306

Showing the first eight; more decompositions exist.
