Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666800, here are decompositions:

  • 3 + 8666797 = 8666800
  • 17 + 8666783 = 8666800
  • 53 + 8666747 = 8666800
  • 89 + 8666711 = 8666800
  • 173 + 8666627 = 8666800
  • 257 + 8666543 = 8666800
  • 281 + 8666519 = 8666800
  • 383 + 8666417 = 8666800

Showing the first eight; more decompositions exist.
