Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647964, here are decompositions:

  • 37 + 8647927 = 8647964
  • 67 + 8647897 = 8647964
  • 163 + 8647801 = 8647964
  • 181 + 8647783 = 8647964
  • 211 + 8647753 = 8647964
  • 307 + 8647657 = 8647964
  • 397 + 8647567 = 8647964
  • 433 + 8647531 = 8647964

Showing the first eight; more decompositions exist.
