Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740224, here are decompositions:

  • 5 + 8740219 = 8740224
  • 37 + 8740187 = 8740224
  • 41 + 8740183 = 8740224
  • 61 + 8740163 = 8740224
  • 67 + 8740157 = 8740224
  • 107 + 8740117 = 8740224
  • 113 + 8740111 = 8740224
  • 127 + 8740097 = 8740224

Showing the first eight; more decompositions exist.
