Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647162, here are decompositions:

  • 5 + 8647157 = 8647162
  • 23 + 8647139 = 8647162
  • 71 + 8647091 = 8647162
  • 101 + 8647061 = 8647162
  • 131 + 8647031 = 8647162
  • 191 + 8646971 = 8647162
  • 233 + 8646929 = 8647162
  • 263 + 8646899 = 8647162

Showing the first eight; more decompositions exist.
