Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454264, here are decompositions:

43 + 31454221 = 31454264
67 + 31454197 = 31454264
73 + 31454191 = 31454264
103 + 31454161 = 31454264
181 + 31454083 = 31454264
211 + 31454053 = 31454264
241 + 31454023 = 31454264
271 + 31453993 = 31454264

Showing the first eight; more decompositions exist.
