Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729790, here are decompositions:

  • 23 + 8729767 = 8729790
  • 61 + 8729729 = 8729790
  • 73 + 8729717 = 8729790
  • 79 + 8729711 = 8729790
  • 101 + 8729689 = 8729790
  • 109 + 8729681 = 8729790
  • 131 + 8729659 = 8729790
  • 149 + 8729641 = 8729790

Showing the first eight; more decompositions exist.
