Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671212, here are decompositions:

  • 19 + 8671193 = 8671212
  • 61 + 8671151 = 8671212
  • 79 + 8671133 = 8671212
  • 113 + 8671099 = 8671212
  • 149 + 8671063 = 8671212
  • 181 + 8671031 = 8671212
  • 223 + 8670989 = 8671212
  • 269 + 8670943 = 8671212

Showing the first eight; more decompositions exist.
