Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640484, here are decompositions:

  • 3 + 8640481 = 8640484
  • 197 + 8640287 = 8640484
  • 233 + 8640251 = 8640484
  • 263 + 8640221 = 8640484
  • 467 + 8640017 = 8640484
  • 563 + 8639921 = 8640484
  • 647 + 8639837 = 8640484
  • 773 + 8639711 = 8640484

Showing the first eight; more decompositions exist.
