Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547324, here are decompositions:

7 + 31547317 = 31547324
37 + 31547287 = 31547324
43 + 31547281 = 31547324
163 + 31547161 = 31547324
181 + 31547143 = 31547324
223 + 31547101 = 31547324
337 + 31546987 = 31547324
433 + 31546891 = 31547324

Showing the first eight; more decompositions exist.
