Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636400, here are decompositions:

  • 11 + 8636389 = 8636400
  • 13 + 8636387 = 8636400
  • 23 + 8636377 = 8636400
  • 53 + 8636347 = 8636400
  • 131 + 8636269 = 8636400
  • 137 + 8636263 = 8636400
  • 139 + 8636261 = 8636400
  • 163 + 8636237 = 8636400

Showing the first eight; more decompositions exist.
