Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476306, here are decompositions:

23 + 31476283 = 31476306
67 + 31476239 = 31476306
137 + 31476169 = 31476306
149 + 31476157 = 31476306
157 + 31476149 = 31476306
163 + 31476143 = 31476306
193 + 31476113 = 31476306
233 + 31476073 = 31476306

Showing the first eight; more decompositions exist.
