Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76666, here are decompositions:

  • 17 + 76649 = 76666
  • 59 + 76607 = 76666
  • 173 + 76493 = 76666
  • 179 + 76487 = 76666
  • 263 + 76403 = 76666
  • 383 + 76283 = 76666
  • 503 + 76163 = 76666
  • 509 + 76157 = 76666

Showing the first eight; more decompositions exist.
