Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457976, here are decompositions:

7 + 31457969 = 31457976
47 + 31457929 = 31457976
73 + 31457903 = 31457976
107 + 31457869 = 31457976
127 + 31457849 = 31457976
157 + 31457819 = 31457976
223 + 31457753 = 31457976
233 + 31457743 = 31457976

Showing the first eight; more decompositions exist.
