Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547262, here are decompositions:

31 + 31547231 = 31547262
53 + 31547209 = 31547262
59 + 31547203 = 31547262
101 + 31547161 = 31547262
199 + 31547063 = 31547262
223 + 31547039 = 31547262
281 + 31546981 = 31547262
293 + 31546969 = 31547262

Showing the first eight; more decompositions exist.
