Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454006, here are decompositions:

13 + 31453993 = 31454006
37 + 31453969 = 31454006
97 + 31453909 = 31454006
109 + 31453897 = 31454006
127 + 31453879 = 31454006
139 + 31453867 = 31454006
193 + 31453813 = 31454006
223 + 31453783 = 31454006

Showing the first eight; more decompositions exist.
