Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99788, here are decompositions:

  • 67 + 99721 = 99788
  • 79 + 99709 = 99788
  • 109 + 99679 = 99788
  • 127 + 99661 = 99788
  • 181 + 99607 = 99788
  • 211 + 99577 = 99788
  • 229 + 99559 = 99788
  • 349 + 99439 = 99788

Showing the first eight; more decompositions exist.
