Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80780, here are decompositions:

  • 3 + 80777 = 80780
  • 19 + 80761 = 80780
  • 31 + 80749 = 80780
  • 43 + 80737 = 80780
  • 67 + 80713 = 80780
  • 79 + 80701 = 80780
  • 97 + 80683 = 80780
  • 103 + 80677 = 80780

Showing the first eight; more decompositions exist.
