Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458950, here are decompositions:

13 + 31458937 = 31458950
37 + 31458913 = 31458950
43 + 31458907 = 31458950
151 + 31458799 = 31458950
163 + 31458787 = 31458950
241 + 31458709 = 31458950
283 + 31458667 = 31458950
307 + 31458643 = 31458950

Showing the first eight; more decompositions exist.
