Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547466, here are decompositions:

7 + 31547459 = 31547466
17 + 31547449 = 31547466
53 + 31547413 = 31547466
109 + 31547357 = 31547466
127 + 31547339 = 31547466
149 + 31547317 = 31547466
163 + 31547303 = 31547466
179 + 31547287 = 31547466

Showing the first eight; more decompositions exist.
