Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666160, here are decompositions:

  • 7 + 8666153 = 8666160
  • 23 + 8666137 = 8666160
  • 67 + 8666093 = 8666160
  • 101 + 8666059 = 8666160
  • 103 + 8666057 = 8666160
  • 109 + 8666051 = 8666160
  • 137 + 8666023 = 8666160
  • 193 + 8665967 = 8666160

Showing the first eight; more decompositions exist.
