Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678500, here are decompositions:

  • 53 + 8678447 = 8678500
  • 101 + 8678399 = 8678500
  • 107 + 8678393 = 8678500
  • 137 + 8678363 = 8678500
  • 167 + 8678333 = 8678500
  • 263 + 8678237 = 8678500
  • 353 + 8678147 = 8678500
  • 359 + 8678141 = 8678500

Showing the first eight; more decompositions exist.
