Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17782, here are decompositions:

  • 53 + 17729 = 17782
  • 101 + 17681 = 17782
  • 113 + 17669 = 17782
  • 173 + 17609 = 17782
  • 263 + 17519 = 17782
  • 293 + 17489 = 17782
  • 311 + 17471 = 17782
  • 389 + 17393 = 17782

Showing the first eight; more decompositions exist.
