Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622512, here are decompositions:

  • 13 + 8622499 = 8622512
  • 43 + 8622469 = 8622512
  • 139 + 8622373 = 8622512
  • 181 + 8622331 = 8622512
  • 211 + 8622301 = 8622512
  • 271 + 8622241 = 8622512
  • 523 + 8621989 = 8622512
  • 541 + 8621971 = 8622512

Showing the first eight; more decompositions exist.
