Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664688, here are decompositions:

  • 17 + 8664671 = 8664688
  • 107 + 8664581 = 8664688
  • 257 + 8664431 = 8664688
  • 269 + 8664419 = 8664688
  • 311 + 8664377 = 8664688
  • 359 + 8664329 = 8664688
  • 701 + 8663987 = 8664688
  • 719 + 8663969 = 8664688

Showing the first eight; more decompositions exist.
