Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729224, here are decompositions:

  • 3 + 8729221 = 8729224
  • 5 + 8729219 = 8729224
  • 17 + 8729207 = 8729224
  • 41 + 8729183 = 8729224
  • 83 + 8729141 = 8729224
  • 107 + 8729117 = 8729224
  • 131 + 8729093 = 8729224
  • 167 + 8729057 = 8729224

Showing the first eight; more decompositions exist.
