Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547326, here are decompositions:

23 + 31547303 = 31547326
29 + 31547297 = 31547326
59 + 31547267 = 31547326
149 + 31547177 = 31547326
179 + 31547147 = 31547326
197 + 31547129 = 31547326
233 + 31547093 = 31547326
263 + 31547063 = 31547326

Showing the first eight; more decompositions exist.
