Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454028, here are decompositions:

5 + 31454023 = 31454028
31 + 31453997 = 31454028
37 + 31453991 = 31454028
59 + 31453969 = 31454028
71 + 31453957 = 31454028
97 + 31453931 = 31454028
131 + 31453897 = 31454028
149 + 31453879 = 31454028

Showing the first eight; more decompositions exist.
