Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99912, here are decompositions:

  • 5 + 99907 = 99912
  • 11 + 99901 = 99912
  • 31 + 99881 = 99912
  • 41 + 99871 = 99912
  • 53 + 99859 = 99912
  • 73 + 99839 = 99912
  • 79 + 99833 = 99912
  • 83 + 99829 = 99912

Showing the first eight; more decompositions exist.
