Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99866, here are decompositions:

  • 7 + 99859 = 99866
  • 37 + 99829 = 99866
  • 43 + 99823 = 99866
  • 73 + 99793 = 99866
  • 79 + 99787 = 99866
  • 157 + 99709 = 99866
  • 199 + 99667 = 99866
  • 223 + 99643 = 99866

Showing the first eight; more decompositions exist.
