Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667688, here are decompositions:

  • 11 + 8667677 = 8667688
  • 47 + 8667641 = 8667688
  • 149 + 8667539 = 8667688
  • 167 + 8667521 = 8667688
  • 191 + 8667497 = 8667688
  • 257 + 8667431 = 8667688
  • 269 + 8667419 = 8667688
  • 311 + 8667377 = 8667688

Showing the first eight; more decompositions exist.
