Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547348, here are decompositions:

31 + 31547317 = 31547348
61 + 31547287 = 31547348
67 + 31547281 = 31547348
139 + 31547209 = 31547348
271 + 31547077 = 31547348
367 + 31546981 = 31547348
379 + 31546969 = 31547348
439 + 31546909 = 31547348

Showing the first eight; more decompositions exist.
