Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674320, here are decompositions:

  • 13 + 8674307 = 8674320
  • 71 + 8674249 = 8674320
  • 107 + 8674213 = 8674320
  • 211 + 8674109 = 8674320
  • 229 + 8674091 = 8674320
  • 233 + 8674087 = 8674320
  • 251 + 8674069 = 8674320
  • 271 + 8674049 = 8674320

Showing the first eight; more decompositions exist.
