Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476150, here are decompositions:

7 + 31476143 = 31476150
31 + 31476119 = 31476150
37 + 31476113 = 31476150
53 + 31476097 = 31476150
137 + 31476013 = 31476150
197 + 31475953 = 31476150
239 + 31475911 = 31476150
241 + 31475909 = 31476150

Showing the first eight; more decompositions exist.
