Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454254, here are decompositions:

5 + 31454249 = 31454254
53 + 31454201 = 31454254
107 + 31454147 = 31454254
131 + 31454123 = 31454254
137 + 31454117 = 31454254
173 + 31454081 = 31454254
257 + 31453997 = 31454254
263 + 31453991 = 31454254

Showing the first eight; more decompositions exist.
