Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617858, here are decompositions:

  • 59 + 8617799 = 8617858
  • 71 + 8617787 = 8617858
  • 89 + 8617769 = 8617858
  • 311 + 8617547 = 8617858
  • 419 + 8617439 = 8617858
  • 461 + 8617397 = 8617858
  • 467 + 8617391 = 8617858
  • 647 + 8617211 = 8617858

Showing the first eight; more decompositions exist.
