Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547676, here are decompositions:

5 + 31547671 = 31547676
47 + 31547629 = 31547676
59 + 31547617 = 31547676
67 + 31547609 = 31547676
137 + 31547539 = 31547676
157 + 31547519 = 31547676
197 + 31547479 = 31547676
227 + 31547449 = 31547676

Showing the first eight; more decompositions exist.
