Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640262, here are decompositions:

  • 3 + 8640259 = 8640262
  • 11 + 8640251 = 8640262
  • 41 + 8640221 = 8640262
  • 101 + 8640161 = 8640262
  • 311 + 8639951 = 8640262
  • 353 + 8639909 = 8640262
  • 359 + 8639903 = 8640262
  • 443 + 8639819 = 8640262

Showing the first eight; more decompositions exist.
