Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547484, here are decompositions:

5 + 31547479 = 31547484
13 + 31547471 = 31547484
43 + 31547441 = 31547484
71 + 31547413 = 31547484
127 + 31547357 = 31547484
167 + 31547317 = 31547484
181 + 31547303 = 31547484
197 + 31547287 = 31547484

Showing the first eight; more decompositions exist.
