Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51724, here are decompositions:

  • 3 + 51721 = 51724
  • 5 + 51719 = 51724
  • 11 + 51713 = 51724
  • 41 + 51683 = 51724
  • 131 + 51593 = 51724
  • 173 + 51551 = 51724
  • 251 + 51473 = 51724
  • 263 + 51461 = 51724

Showing the first eight; more decompositions exist.
