Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458984, here are decompositions:

17 + 31458967 = 31458984
31 + 31458953 = 31458984
47 + 31458937 = 31458984
61 + 31458923 = 31458984
71 + 31458913 = 31458984
83 + 31458901 = 31458984
163 + 31458821 = 31458984
197 + 31458787 = 31458984

Showing the first eight; more decompositions exist.
