Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641562, here are decompositions:

  • 19 + 8641543 = 8641562
  • 43 + 8641519 = 8641562
  • 109 + 8641453 = 8641562
  • 211 + 8641351 = 8641562
  • 313 + 8641249 = 8641562
  • 331 + 8641231 = 8641562
  • 499 + 8641063 = 8641562
  • 613 + 8640949 = 8641562

Showing the first eight; more decompositions exist.
