Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 682, here are decompositions:

  • 5 + 677 = 682
  • 23 + 659 = 682
  • 29 + 653 = 682
  • 41 + 641 = 682
  • 83 + 599 = 682
  • 89 + 593 = 682
  • 113 + 569 = 682
  • 173 + 509 = 682

Showing the first eight; more decompositions exist.
