Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81976, here are decompositions:

  • 3 + 81973 = 81976
  • 5 + 81971 = 81976
  • 23 + 81953 = 81976
  • 47 + 81929 = 81976
  • 107 + 81869 = 81976
  • 137 + 81839 = 81976
  • 227 + 81749 = 81976
  • 239 + 81737 = 81976

Showing the first eight; more decompositions exist.
