Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66678, here are decompositions:

  • 61 + 66617 = 66678
  • 107 + 66571 = 66678
  • 109 + 66569 = 66678
  • 137 + 66541 = 66678
  • 149 + 66529 = 66678
  • 179 + 66499 = 66678
  • 211 + 66467 = 66678
  • 229 + 66449 = 66678

Showing the first eight; more decompositions exist.
