Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454196, here are decompositions:

5 + 31454191 = 31454196
47 + 31454149 = 31454196
73 + 31454123 = 31454196
79 + 31454117 = 31454196
113 + 31454083 = 31454196
173 + 31454023 = 31454196
199 + 31453997 = 31454196
227 + 31453969 = 31454196

Showing the first eight; more decompositions exist.
