Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454276, here are decompositions:

13 + 31454263 = 31454276
79 + 31454197 = 31454276
127 + 31454149 = 31454276
193 + 31454083 = 31454276
199 + 31454077 = 31454276
223 + 31454053 = 31454276
283 + 31453993 = 31454276
307 + 31453969 = 31454276

Showing the first eight; more decompositions exist.
