Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547404, here are decompositions:

47 + 31547357 = 31547404
101 + 31547303 = 31547404
107 + 31547297 = 31547404
137 + 31547267 = 31547404
173 + 31547231 = 31547404
227 + 31547177 = 31547404
257 + 31547147 = 31547404
311 + 31547093 = 31547404

Showing the first eight; more decompositions exist.
