Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80920, here are decompositions:

  • 3 + 80917 = 80920
  • 11 + 80909 = 80920
  • 23 + 80897 = 80920
  • 71 + 80849 = 80920
  • 89 + 80831 = 80920
  • 101 + 80819 = 80920
  • 131 + 80789 = 80920
  • 137 + 80783 = 80920

Showing the first eight; more decompositions exist.
