Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99918, here are decompositions:

  • 11 + 99907 = 99918
  • 17 + 99901 = 99918
  • 37 + 99881 = 99918
  • 41 + 99877 = 99918
  • 47 + 99871 = 99918
  • 59 + 99859 = 99918
  • 79 + 99839 = 99918
  • 89 + 99829 = 99918

Showing the first eight; more decompositions exist.
