Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628404, here are decompositions:

  • 223 + 8628181 = 8628404
  • 283 + 8628121 = 8628404
  • 307 + 8628097 = 8628404
  • 373 + 8628031 = 8628404
  • 397 + 8628007 = 8628404
  • 457 + 8627947 = 8628404
  • 571 + 8627833 = 8628404
  • 691 + 8627713 = 8628404

Showing the first eight; more decompositions exist.
