Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454344, here are decompositions:

23 + 31454321 = 31454344
197 + 31454147 = 31454344
227 + 31454117 = 31454344
263 + 31454081 = 31454344
347 + 31453997 = 31454344
353 + 31453991 = 31454344
401 + 31453943 = 31454344
461 + 31453883 = 31454344

Showing the first eight; more decompositions exist.
