Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674680, here are decompositions:

  • 13 + 8674667 = 8674680
  • 61 + 8674619 = 8674680
  • 103 + 8674577 = 8674680
  • 109 + 8674571 = 8674680
  • 127 + 8674553 = 8674680
  • 137 + 8674543 = 8674680
  • 149 + 8674531 = 8674680
  • 181 + 8674499 = 8674680

Showing the first eight; more decompositions exist.
