Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671740, here are decompositions:

  • 19 + 8671721 = 8671740
  • 29 + 8671711 = 8671740
  • 31 + 8671709 = 8671740
  • 43 + 8671697 = 8671740
  • 71 + 8671669 = 8671740
  • 101 + 8671639 = 8671740
  • 107 + 8671633 = 8671740
  • 109 + 8671631 = 8671740

Showing the first eight; more decompositions exist.
