Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720068, here are decompositions:

  • 11 + 8720057 = 8720068
  • 41 + 8720027 = 8720068
  • 107 + 8719961 = 8720068
  • 251 + 8719817 = 8720068
  • 491 + 8719577 = 8720068
  • 647 + 8719421 = 8720068
  • 677 + 8719391 = 8720068
  • 701 + 8719367 = 8720068

Showing the first eight; more decompositions exist.
