Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663980, here are decompositions:

  • 11 + 8663969 = 8663980
  • 173 + 8663807 = 8663980
  • 239 + 8663741 = 8663980
  • 293 + 8663687 = 8663980
  • 359 + 8663621 = 8663980
  • 401 + 8663579 = 8663980
  • 443 + 8663537 = 8663980
  • 461 + 8663519 = 8663980

Showing the first eight; more decompositions exist.
