Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454016, here are decompositions:

19 + 31453997 = 31454016
23 + 31453993 = 31454016
47 + 31453969 = 31454016
59 + 31453957 = 31454016
73 + 31453943 = 31454016
107 + 31453909 = 31454016
137 + 31453879 = 31454016
149 + 31453867 = 31454016

Showing the first eight; more decompositions exist.
