Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547708, here are decompositions:

7 + 31547701 = 31547708
37 + 31547671 = 31547708
67 + 31547641 = 31547708
79 + 31547629 = 31547708
151 + 31547557 = 31547708
229 + 31547479 = 31547708
421 + 31547287 = 31547708
499 + 31547209 = 31547708

Showing the first eight; more decompositions exist.
