Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18784, here are decompositions:

  • 11 + 18773 = 18784
  • 41 + 18743 = 18784
  • 53 + 18731 = 18784
  • 71 + 18713 = 18784
  • 83 + 18701 = 18784
  • 113 + 18671 = 18784
  • 167 + 18617 = 18784
  • 191 + 18593 = 18784

Showing the first eight; more decompositions exist.
