Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666900, here are decompositions:

  • 19 + 8666881 = 8666900
  • 37 + 8666863 = 8666900
  • 61 + 8666839 = 8666900
  • 103 + 8666797 = 8666900
  • 127 + 8666773 = 8666900
  • 367 + 8666533 = 8666900
  • 409 + 8666491 = 8666900
  • 421 + 8666479 = 8666900

Showing the first eight; more decompositions exist.
