Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647912, here are decompositions:

  • 23 + 8647889 = 8647912
  • 89 + 8647823 = 8647912
  • 173 + 8647739 = 8647912
  • 401 + 8647511 = 8647912
  • 443 + 8647469 = 8647912
  • 503 + 8647409 = 8647912
  • 521 + 8647391 = 8647912
  • 563 + 8647349 = 8647912

Showing the first eight; more decompositions exist.
