Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547188, here are decompositions:

11 + 31547177 = 31547188
41 + 31547147 = 31547188
59 + 31547129 = 31547188
149 + 31547039 = 31547188
191 + 31546997 = 31547188
251 + 31546937 = 31547188
389 + 31546799 = 31547188
467 + 31546721 = 31547188

Showing the first eight; more decompositions exist.
