Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476350, here are decompositions:

7 + 31476343 = 31476350
67 + 31476283 = 31476350
163 + 31476187 = 31476350
181 + 31476169 = 31476350
193 + 31476157 = 31476350
277 + 31476073 = 31476350
337 + 31476013 = 31476350
397 + 31475953 = 31476350

Showing the first eight; more decompositions exist.
