Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66250, here are decompositions:

  • 11 + 66239 = 66250
  • 29 + 66221 = 66250
  • 59 + 66191 = 66250
  • 71 + 66179 = 66250
  • 89 + 66161 = 66250
  • 113 + 66137 = 66250
  • 167 + 66083 = 66250
  • 179 + 66071 = 66250

Showing the first eight; more decompositions exist.
