Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487668, here are decompositions:

  • 11 + 487657 = 487668
  • 17 + 487651 = 487668
  • 19 + 487649 = 487668
  • 31 + 487637 = 487668
  • 61 + 487607 = 487668
  • 67 + 487601 = 487668
  • 79 + 487589 = 487668
  • 107 + 487561 = 487668

Showing the first eight; more decompositions exist.
