Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644200, here are decompositions:

  • 13 + 8644187 = 8644200
  • 29 + 8644171 = 8644200
  • 43 + 8644157 = 8644200
  • 53 + 8644147 = 8644200
  • 109 + 8644091 = 8644200
  • 139 + 8644061 = 8644200
  • 151 + 8644049 = 8644200
  • 181 + 8644019 = 8644200

Showing the first eight; more decompositions exist.
