Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607780, here are decompositions:

  • 11 + 8607769 = 8607780
  • 31 + 8607749 = 8607780
  • 43 + 8607737 = 8607780
  • 47 + 8607733 = 8607780
  • 67 + 8607713 = 8607780
  • 107 + 8607673 = 8607780
  • 113 + 8607667 = 8607780
  • 127 + 8607653 = 8607780

Showing the first eight; more decompositions exist.
