Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481428, here are decompositions:

  • 11 + 481417 = 481428
  • 19 + 481409 = 481428
  • 41 + 481387 = 481428
  • 127 + 481301 = 481428
  • 131 + 481297 = 481428
  • 179 + 481249 = 481428
  • 197 + 481231 = 481428
  • 229 + 481199 = 481428

Showing the first eight; more decompositions exist.
