Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743920, here are decompositions:

  • 7 + 8743913 = 8743920
  • 19 + 8743901 = 8743920
  • 37 + 8743883 = 8743920
  • 41 + 8743879 = 8743920
  • 67 + 8743853 = 8743920
  • 83 + 8743837 = 8743920
  • 103 + 8743817 = 8743920
  • 113 + 8743807 = 8743920

Showing the first eight; more decompositions exist.
