Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689790, here are decompositions:

  • 13 + 8689777 = 8689790
  • 37 + 8689753 = 8689790
  • 61 + 8689729 = 8689790
  • 79 + 8689711 = 8689790
  • 103 + 8689687 = 8689790
  • 163 + 8689627 = 8689790
  • 181 + 8689609 = 8689790
  • 199 + 8689591 = 8689790

Showing the first eight; more decompositions exist.
