Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656250, here are decompositions:

  • 19 + 8656231 = 8656250
  • 61 + 8656189 = 8656250
  • 73 + 8656177 = 8656250
  • 79 + 8656171 = 8656250
  • 103 + 8656147 = 8656250
  • 157 + 8656093 = 8656250
  • 181 + 8656069 = 8656250
  • 193 + 8656057 = 8656250

Showing the first eight; more decompositions exist.
