Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647874, here are decompositions:

  • 73 + 8647801 = 8647874
  • 163 + 8647711 = 8647874
  • 307 + 8647567 = 8647874
  • 337 + 8647537 = 8647874
  • 373 + 8647501 = 8647874
  • 457 + 8647417 = 8647874
  • 463 + 8647411 = 8647874
  • 601 + 8647273 = 8647874

Showing the first eight; more decompositions exist.
