Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454198, here are decompositions:

7 + 31454191 = 31454198
37 + 31454161 = 31454198
229 + 31453969 = 31454198
241 + 31453957 = 31454198
331 + 31453867 = 31454198
487 + 31453711 = 31454198
499 + 31453699 = 31454198
547 + 31453651 = 31454198

Showing the first eight; more decompositions exist.
