Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81924, here are decompositions:

  • 5 + 81919 = 81924
  • 23 + 81901 = 81924
  • 41 + 81883 = 81924
  • 71 + 81853 = 81924
  • 107 + 81817 = 81924
  • 151 + 81773 = 81924
  • 163 + 81761 = 81924
  • 197 + 81727 = 81924

Showing the first eight; more decompositions exist.
