Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81848, here are decompositions:

  • 31 + 81817 = 81848
  • 79 + 81769 = 81848
  • 181 + 81667 = 81848
  • 199 + 81649 = 81848
  • 211 + 81637 = 81848
  • 229 + 81619 = 81848
  • 331 + 81517 = 81848
  • 409 + 81439 = 81848

Showing the first eight; more decompositions exist.
