Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453934, here are decompositions:

3 + 31453931 = 31453934
37 + 31453897 = 31453934
67 + 31453867 = 31453934
151 + 31453783 = 31453934
223 + 31453711 = 31453934
283 + 31453651 = 31453934
433 + 31453501 = 31453934
487 + 31453447 = 31453934

Showing the first eight; more decompositions exist.
