Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8266, here are decompositions:

  • 3 + 8263 = 8266
  • 23 + 8243 = 8266
  • 29 + 8237 = 8266
  • 47 + 8219 = 8266
  • 149 + 8117 = 8266
  • 173 + 8093 = 8266
  • 179 + 8087 = 8266
  • 197 + 8069 = 8266

Showing the first eight; more decompositions exist.
