Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458150, here are decompositions:

19 + 31458131 = 31458150
37 + 31458113 = 31458150
67 + 31458083 = 31458150
89 + 31458061 = 31458150
137 + 31458013 = 31458150
151 + 31457999 = 31458150
181 + 31457969 = 31458150
239 + 31457911 = 31458150

Showing the first eight; more decompositions exist.
