Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99818, here are decompositions:

  • 31 + 99787 = 99818
  • 97 + 99721 = 99818
  • 109 + 99709 = 99818
  • 139 + 99679 = 99818
  • 151 + 99667 = 99818
  • 157 + 99661 = 99818
  • 211 + 99607 = 99818
  • 241 + 99577 = 99818

Showing the first eight; more decompositions exist.
