Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618550, here are decompositions:

  • 67 + 8618483 = 8618550
  • 71 + 8618479 = 8618550
  • 107 + 8618443 = 8618550
  • 137 + 8618413 = 8618550
  • 163 + 8618387 = 8618550
  • 173 + 8618377 = 8618550
  • 211 + 8618339 = 8618550
  • 223 + 8618327 = 8618550

Showing the first eight; more decompositions exist.
