Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33626178, here are decompositions:

  • 67 + 33626111 = 33626178
  • 71 + 33626107 = 33626178
  • 101 + 33626077 = 33626178
  • 167 + 33626011 = 33626178
  • 191 + 33625987 = 33626178
  • 269 + 33625909 = 33626178
  • 281 + 33625897 = 33626178
  • 337 + 33625841 = 33626178

Showing the first eight; more decompositions exist.
