Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453974, here are decompositions:

5 + 31453969 = 31453974
17 + 31453957 = 31453974
31 + 31453943 = 31453974
43 + 31453931 = 31453974
107 + 31453867 = 31453974
151 + 31453823 = 31453974
191 + 31453783 = 31453974
241 + 31453733 = 31453974

Showing the first eight; more decompositions exist.
