Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 706, here are decompositions:

  • 5 + 701 = 706
  • 23 + 683 = 706
  • 29 + 677 = 706
  • 47 + 659 = 706
  • 53 + 653 = 706
  • 59 + 647 = 706
  • 89 + 617 = 706
  • 107 + 599 = 706

Showing the first eight; more decompositions exist.
