Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602780, here are decompositions:

  • 3 + 8602777 = 8602780
  • 23 + 8602757 = 8602780
  • 29 + 8602751 = 8602780
  • 89 + 8602691 = 8602780
  • 101 + 8602679 = 8602780
  • 107 + 8602673 = 8602780
  • 149 + 8602631 = 8602780
  • 269 + 8602511 = 8602780

Showing the first eight; more decompositions exist.
