Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638300, here are decompositions:

  • 17 + 8638283 = 8638300
  • 23 + 8638277 = 8638300
  • 53 + 8638247 = 8638300
  • 59 + 8638241 = 8638300
  • 71 + 8638229 = 8638300
  • 101 + 8638199 = 8638300
  • 113 + 8638187 = 8638300
  • 149 + 8638151 = 8638300

Showing the first eight; more decompositions exist.
