Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690880, here are decompositions:

  • 13 + 8690867 = 8690880
  • 53 + 8690827 = 8690880
  • 59 + 8690821 = 8690880
  • 67 + 8690813 = 8690880
  • 83 + 8690797 = 8690880
  • 97 + 8690783 = 8690880
  • 113 + 8690767 = 8690880
  • 139 + 8690741 = 8690880

Showing the first eight; more decompositions exist.
