Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43664, here are decompositions:

  • 3 + 43661 = 43664
  • 13 + 43651 = 43664
  • 31 + 43633 = 43664
  • 37 + 43627 = 43664
  • 67 + 43597 = 43664
  • 73 + 43591 = 43664
  • 223 + 43441 = 43664
  • 373 + 43291 = 43664

Showing the first eight; more decompositions exist.
