Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77216, here are decompositions:

  • 3 + 77213 = 77216
  • 79 + 77137 = 77216
  • 193 + 77023 = 77216
  • 199 + 77017 = 77216
  • 379 + 76837 = 77216
  • 397 + 76819 = 77216
  • 439 + 76777 = 77216
  • 463 + 76753 = 77216

Showing the first eight; more decompositions exist.
