Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6456, here are decompositions:

  • 5 + 6451 = 6456
  • 7 + 6449 = 6456
  • 29 + 6427 = 6456
  • 59 + 6397 = 6456
  • 67 + 6389 = 6456
  • 83 + 6373 = 6456
  • 89 + 6367 = 6456
  • 97 + 6359 = 6456

Showing the first eight; more decompositions exist.
