Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637224, here are decompositions:

  • 61 + 8637163 = 8637224
  • 73 + 8637151 = 8637224
  • 157 + 8637067 = 8637224
  • 163 + 8637061 = 8637224
  • 307 + 8636917 = 8637224
  • 313 + 8636911 = 8637224
  • 331 + 8636893 = 8637224
  • 367 + 8636857 = 8637224

Showing the first eight; more decompositions exist.
