Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639480, here are decompositions:

  • 19 + 8639461 = 8639480
  • 37 + 8639443 = 8639480
  • 67 + 8639413 = 8639480
  • 79 + 8639401 = 8639480
  • 181 + 8639299 = 8639480
  • 229 + 8639251 = 8639480
  • 331 + 8639149 = 8639480
  • 337 + 8639143 = 8639480

Showing the first eight; more decompositions exist.
