Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547256, here are decompositions:

47 + 31547209 = 31547256
53 + 31547203 = 31547256
79 + 31547177 = 31547256
109 + 31547147 = 31547256
113 + 31547143 = 31547256
127 + 31547129 = 31547256
163 + 31547093 = 31547256
179 + 31547077 = 31547256

Showing the first eight; more decompositions exist.
