Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73980, here are decompositions:

  • 7 + 73973 = 73980
  • 19 + 73961 = 73980
  • 29 + 73951 = 73980
  • 37 + 73943 = 73980
  • 41 + 73939 = 73980
  • 73 + 73907 = 73980
  • 83 + 73897 = 73980
  • 97 + 73883 = 73980

Showing the first eight; more decompositions exist.
