Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605218, here are decompositions:

  • 7 + 8605211 = 8605218
  • 31 + 8605187 = 8605218
  • 47 + 8605171 = 8605218
  • 59 + 8605159 = 8605218
  • 71 + 8605147 = 8605218
  • 157 + 8605061 = 8605218
  • 199 + 8605019 = 8605218
  • 227 + 8604991 = 8605218

Showing the first eight; more decompositions exist.
