Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66644, here are decompositions:

  • 43 + 66601 = 66644
  • 73 + 66571 = 66644
  • 103 + 66541 = 66644
  • 181 + 66463 = 66644
  • 241 + 66403 = 66644
  • 271 + 66373 = 66644
  • 283 + 66361 = 66644
  • 307 + 66337 = 66644

Showing the first eight; more decompositions exist.
