Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66378, here are decompositions:

  • 5 + 66373 = 66378
  • 17 + 66361 = 66378
  • 19 + 66359 = 66378
  • 31 + 66347 = 66378
  • 41 + 66337 = 66378
  • 107 + 66271 = 66378
  • 139 + 66239 = 66378
  • 157 + 66221 = 66378

Showing the first eight; more decompositions exist.
