Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639766, here are decompositions:

  • 13 + 8639753 = 8639766
  • 17 + 8639749 = 8639766
  • 19 + 8639747 = 8639766
  • 53 + 8639713 = 8639766
  • 103 + 8639663 = 8639766
  • 127 + 8639639 = 8639766
  • 167 + 8639599 = 8639766
  • 199 + 8639567 = 8639766

Showing the first eight; more decompositions exist.
