Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547226, here are decompositions:

17 + 31547209 = 31547226
23 + 31547203 = 31547226
79 + 31547147 = 31547226
83 + 31547143 = 31547226
97 + 31547129 = 31547226
149 + 31547077 = 31547226
163 + 31547063 = 31547226
223 + 31547003 = 31547226

Showing the first eight; more decompositions exist.
