Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77560, here are decompositions:

  • 3 + 77557 = 77560
  • 11 + 77549 = 77560
  • 17 + 77543 = 77560
  • 47 + 77513 = 77560
  • 71 + 77489 = 77560
  • 83 + 77477 = 77560
  • 89 + 77471 = 77560
  • 113 + 77447 = 77560

Showing the first eight; more decompositions exist.
