Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454348, here are decompositions:

127 + 31454221 = 31454348
151 + 31454197 = 31454348
157 + 31454191 = 31454348
199 + 31454149 = 31454348
271 + 31454077 = 31454348
379 + 31453969 = 31454348
439 + 31453909 = 31454348
1327 + 31453021 = 31454348

Showing the first eight; more decompositions exist.
