Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640038, here are decompositions:

  • 37 + 8640001 = 8640038
  • 61 + 8639977 = 8640038
  • 139 + 8639899 = 8640038
  • 229 + 8639809 = 8640038
  • 241 + 8639797 = 8640038
  • 439 + 8639599 = 8640038
  • 487 + 8639551 = 8640038
  • 499 + 8639539 = 8640038

Showing the first eight; more decompositions exist.
