Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458954, here are decompositions:

17 + 31458937 = 31458954
31 + 31458923 = 31458954
41 + 31458913 = 31458954
47 + 31458907 = 31458954
53 + 31458901 = 31458954
157 + 31458797 = 31458954
167 + 31458787 = 31458954
193 + 31458761 = 31458954

Showing the first eight; more decompositions exist.
