Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649216, here are decompositions:

  • 5 + 8649211 = 8649216
  • 19 + 8649197 = 8649216
  • 29 + 8649187 = 8649216
  • 113 + 8649103 = 8649216
  • 137 + 8649079 = 8649216
  • 167 + 8649049 = 8649216
  • 193 + 8649023 = 8649216
  • 263 + 8648953 = 8649216

Showing the first eight; more decompositions exist.
