Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650390, here are decompositions:

  • 29 + 8650361 = 8650390
  • 71 + 8650319 = 8650390
  • 83 + 8650307 = 8650390
  • 107 + 8650283 = 8650390
  • 131 + 8650259 = 8650390
  • 137 + 8650253 = 8650390
  • 167 + 8650223 = 8650390
  • 173 + 8650217 = 8650390

Showing the first eight; more decompositions exist.
