Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720698, here are decompositions:

  • 5 + 8720693 = 8720698
  • 11 + 8720687 = 8720698
  • 17 + 8720681 = 8720698
  • 71 + 8720627 = 8720698
  • 101 + 8720597 = 8720698
  • 167 + 8720531 = 8720698
  • 227 + 8720471 = 8720698
  • 251 + 8720447 = 8720698

Showing the first eight; more decompositions exist.
