Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99728, here are decompositions:

  • 7 + 99721 = 99728
  • 19 + 99709 = 99728
  • 61 + 99667 = 99728
  • 67 + 99661 = 99728
  • 151 + 99577 = 99728
  • 157 + 99571 = 99728
  • 199 + 99529 = 99728
  • 241 + 99487 = 99728

Showing the first eight; more decompositions exist.
