Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691210, here are decompositions:

  • 23 + 8691187 = 8691210
  • 43 + 8691167 = 8691210
  • 53 + 8691157 = 8691210
  • 83 + 8691127 = 8691210
  • 109 + 8691101 = 8691210
  • 167 + 8691043 = 8691210
  • 191 + 8691019 = 8691210
  • 239 + 8690971 = 8691210

Showing the first eight; more decompositions exist.
