Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623400, here are decompositions:

  • 7 + 8623393 = 8623400
  • 43 + 8623357 = 8623400
  • 61 + 8623339 = 8623400
  • 109 + 8623291 = 8623400
  • 139 + 8623261 = 8623400
  • 151 + 8623249 = 8623400
  • 277 + 8623123 = 8623400
  • 349 + 8623051 = 8623400

Showing the first eight; more decompositions exist.
