Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 700, here are decompositions:

  • 17 + 683 = 700
  • 23 + 677 = 700
  • 41 + 659 = 700
  • 47 + 653 = 700
  • 53 + 647 = 700
  • 59 + 641 = 700
  • 83 + 617 = 700
  • 101 + 599 = 700

Showing the first eight; more decompositions exist.
