Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547510, here are decompositions:

3 + 31547507 = 31547510
31 + 31547479 = 31547510
61 + 31547449 = 31547510
97 + 31547413 = 31547510
193 + 31547317 = 31547510
223 + 31547287 = 31547510
229 + 31547281 = 31547510
307 + 31547203 = 31547510

Showing the first eight; more decompositions exist.
