Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453976, here are decompositions:

7 + 31453969 = 31453976
19 + 31453957 = 31453976
67 + 31453909 = 31453976
79 + 31453897 = 31453976
97 + 31453879 = 31453976
109 + 31453867 = 31453976
163 + 31453813 = 31453976
193 + 31453783 = 31453976

Showing the first eight; more decompositions exist.
