Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482586, here are decompositions:

17 + 31482569 = 31482586
197 + 31482389 = 31482586
293 + 31482293 = 31482586
419 + 31482167 = 31482586
467 + 31482119 = 31482586
503 + 31482083 = 31482586
647 + 31481939 = 31482586
719 + 31481867 = 31482586

Showing the first eight; more decompositions exist.
