Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666480, here are decompositions:

  • 3 + 8666477 = 8666480
  • 37 + 8666443 = 8666480
  • 61 + 8666419 = 8666480
  • 157 + 8666323 = 8666480
  • 211 + 8666269 = 8666480
  • 307 + 8666173 = 8666480
  • 313 + 8666167 = 8666480
  • 421 + 8666059 = 8666480

Showing the first eight; more decompositions exist.
