Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640104, here are decompositions:

  • 103 + 8640001 = 8640104
  • 127 + 8639977 = 8640104
  • 181 + 8639923 = 8640104
  • 241 + 8639863 = 8640104
  • 307 + 8639797 = 8640104
  • 331 + 8639773 = 8640104
  • 457 + 8639647 = 8640104
  • 541 + 8639563 = 8640104

Showing the first eight; more decompositions exist.
