Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672224, here are decompositions:

  • 17 + 8672207 = 8672224
  • 23 + 8672201 = 8672224
  • 47 + 8672177 = 8672224
  • 107 + 8672117 = 8672224
  • 137 + 8672087 = 8672224
  • 233 + 8671991 = 8672224
  • 257 + 8671967 = 8672224
  • 317 + 8671907 = 8672224

Showing the first eight; more decompositions exist.
