Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638876, here are decompositions:

  • 23 + 8638853 = 8638876
  • 149 + 8638727 = 8638876
  • 179 + 8638697 = 8638876
  • 293 + 8638583 = 8638876
  • 359 + 8638517 = 8638876
  • 419 + 8638457 = 8638876
  • 503 + 8638373 = 8638876
  • 557 + 8638319 = 8638876

Showing the first eight; more decompositions exist.
