Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641318, here are decompositions:

  • 17 + 8641301 = 8641318
  • 29 + 8641289 = 8641318
  • 71 + 8641247 = 8641318
  • 107 + 8641211 = 8641318
  • 131 + 8641187 = 8641318
  • 239 + 8641079 = 8641318
  • 311 + 8641007 = 8641318
  • 431 + 8640887 = 8641318

Showing the first eight; more decompositions exist.
