Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660740, here are decompositions:

  • 17 + 8660723 = 8660740
  • 41 + 8660699 = 8660740
  • 47 + 8660693 = 8660740
  • 59 + 8660681 = 8660740
  • 83 + 8660657 = 8660740
  • 131 + 8660609 = 8660740
  • 197 + 8660543 = 8660740
  • 233 + 8660507 = 8660740

Showing the first eight; more decompositions exist.
