Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454374, here are decompositions:

23 + 31454351 = 31454374
53 + 31454321 = 31454374
173 + 31454201 = 31454374
227 + 31454147 = 31454374
251 + 31454123 = 31454374
257 + 31454117 = 31454374
293 + 31454081 = 31454374
383 + 31453991 = 31454374

Showing the first eight; more decompositions exist.
