Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77660, here are decompositions:

  • 13 + 77647 = 77660
  • 19 + 77641 = 77660
  • 43 + 77617 = 77660
  • 73 + 77587 = 77660
  • 97 + 77563 = 77660
  • 103 + 77557 = 77660
  • 109 + 77551 = 77660
  • 139 + 77521 = 77660

Showing the first eight; more decompositions exist.
