Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454266, here are decompositions:

3 + 31454263 = 31454266
17 + 31454249 = 31454266
47 + 31454219 = 31454266
149 + 31454117 = 31454266
269 + 31453997 = 31454266
383 + 31453883 = 31454266
443 + 31453823 = 31454266
587 + 31453679 = 31454266

Showing the first eight; more decompositions exist.
