Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642182, here are decompositions:

  • 23 + 8642159 = 8642182
  • 41 + 8642141 = 8642182
  • 71 + 8642111 = 8642182
  • 83 + 8642099 = 8642182
  • 149 + 8642033 = 8642182
  • 179 + 8642003 = 8642182
  • 191 + 8641991 = 8642182
  • 233 + 8641949 = 8642182

Showing the first eight; more decompositions exist.
