Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29728, here are decompositions:

  • 5 + 29723 = 29728
  • 11 + 29717 = 29728
  • 59 + 29669 = 29728
  • 191 + 29537 = 29728
  • 197 + 29531 = 29728
  • 227 + 29501 = 29728
  • 317 + 29411 = 29728
  • 389 + 29339 = 29728

Showing the first eight; more decompositions exist.
