Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65448, here are decompositions:

  • 11 + 65437 = 65448
  • 29 + 65419 = 65448
  • 41 + 65407 = 65448
  • 67 + 65381 = 65448
  • 139 + 65309 = 65448
  • 179 + 65269 = 65448
  • 181 + 65267 = 65448
  • 191 + 65257 = 65448

Showing the first eight; more decompositions exist.
