Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666494, here are decompositions:

  • 3 + 8666491 = 8666494
  • 17 + 8666477 = 8666494
  • 101 + 8666393 = 8666494
  • 107 + 8666387 = 8666494
  • 113 + 8666381 = 8666494
  • 167 + 8666327 = 8666494
  • 257 + 8666237 = 8666494
  • 293 + 8666201 = 8666494

Showing the first eight; more decompositions exist.
