Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673880, here are decompositions:

  • 3 + 8673877 = 8673880
  • 41 + 8673839 = 8673880
  • 197 + 8673683 = 8673880
  • 269 + 8673611 = 8673880
  • 311 + 8673569 = 8673880
  • 461 + 8673419 = 8673880
  • 491 + 8673389 = 8673880
  • 503 + 8673377 = 8673880

Showing the first eight; more decompositions exist.
