Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650666, here are decompositions:

  • 83 + 8650583 = 8650666
  • 107 + 8650559 = 8650666
  • 149 + 8650517 = 8650666
  • 179 + 8650487 = 8650666
  • 257 + 8650409 = 8650666
  • 347 + 8650319 = 8650666
  • 359 + 8650307 = 8650666
  • 383 + 8650283 = 8650666

Showing the first eight; more decompositions exist.
