Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476006, here are decompositions:

43 + 31475963 = 31476006
53 + 31475953 = 31476006
97 + 31475909 = 31476006
157 + 31475849 = 31476006
179 + 31475827 = 31476006
193 + 31475813 = 31476006
227 + 31475779 = 31476006
229 + 31475777 = 31476006

Showing the first eight; more decompositions exist.
