Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547298, here are decompositions:

11 + 31547287 = 31547298
17 + 31547281 = 31547298
31 + 31547267 = 31547298
37 + 31547261 = 31547298
67 + 31547231 = 31547298
89 + 31547209 = 31547298
137 + 31547161 = 31547298
151 + 31547147 = 31547298

Showing the first eight; more decompositions exist.
