Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80664, here are decompositions:

  • 7 + 80657 = 80664
  • 13 + 80651 = 80664
  • 37 + 80627 = 80664
  • 43 + 80621 = 80664
  • 53 + 80611 = 80664
  • 61 + 80603 = 80664
  • 97 + 80567 = 80664
  • 107 + 80557 = 80664

Showing the first eight; more decompositions exist.
