Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729658, here are decompositions:

  • 11 + 8729647 = 8729658
  • 17 + 8729641 = 8729658
  • 29 + 8729629 = 8729658
  • 37 + 8729621 = 8729658
  • 101 + 8729557 = 8729658
  • 167 + 8729491 = 8729658
  • 191 + 8729467 = 8729658
  • 229 + 8729429 = 8729658

Showing the first eight; more decompositions exist.
