Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47432, here are decompositions:

  • 13 + 47419 = 47432
  • 43 + 47389 = 47432
  • 79 + 47353 = 47432
  • 139 + 47293 = 47432
  • 163 + 47269 = 47432
  • 181 + 47251 = 47432
  • 211 + 47221 = 47432
  • 271 + 47161 = 47432

Showing the first eight; more decompositions exist.
