Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72972, here are decompositions:

  • 13 + 72959 = 72972
  • 19 + 72953 = 72972
  • 23 + 72949 = 72972
  • 41 + 72931 = 72972
  • 61 + 72911 = 72972
  • 71 + 72901 = 72972
  • 79 + 72893 = 72972
  • 83 + 72889 = 72972

Showing the first eight; more decompositions exist.
