Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547658, here are decompositions:

17 + 31547641 = 31547658
29 + 31547629 = 31547658
41 + 31547617 = 31547658
67 + 31547591 = 31547658
101 + 31547557 = 31547658
127 + 31547531 = 31547658
139 + 31547519 = 31547658
151 + 31547507 = 31547658

Showing the first eight; more decompositions exist.
