Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638354, here are decompositions:

  • 5 + 8638349 = 8638354
  • 17 + 8638337 = 8638354
  • 71 + 8638283 = 8638354
  • 107 + 8638247 = 8638354
  • 113 + 8638241 = 8638354
  • 167 + 8638187 = 8638354
  • 233 + 8638121 = 8638354
  • 293 + 8638061 = 8638354

Showing the first eight; more decompositions exist.
