Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623240, here are decompositions:

  • 47 + 8623193 = 8623240
  • 137 + 8623103 = 8623240
  • 167 + 8623073 = 8623240
  • 173 + 8623067 = 8623240
  • 179 + 8623061 = 8623240
  • 257 + 8622983 = 8623240
  • 281 + 8622959 = 8623240
  • 317 + 8622923 = 8623240

Showing the first eight; more decompositions exist.
