Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666928, here are decompositions:

  • 37 + 8666891 = 8666928
  • 47 + 8666881 = 8666928
  • 79 + 8666849 = 8666928
  • 89 + 8666839 = 8666928
  • 131 + 8666797 = 8666928
  • 181 + 8666747 = 8666928
  • 331 + 8666597 = 8666928
  • 337 + 8666591 = 8666928

Showing the first eight; more decompositions exist.
