Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671630, here are decompositions:

  • 41 + 8671589 = 8671630
  • 47 + 8671583 = 8671630
  • 113 + 8671517 = 8671630
  • 131 + 8671499 = 8671630
  • 167 + 8671463 = 8671630
  • 173 + 8671457 = 8671630
  • 263 + 8671367 = 8671630
  • 269 + 8671361 = 8671630

Showing the first eight; more decompositions exist.
