Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672208, here are decompositions:

  • 5 + 8672203 = 8672208
  • 7 + 8672201 = 8672208
  • 31 + 8672177 = 8672208
  • 47 + 8672161 = 8672208
  • 107 + 8672101 = 8672208
  • 109 + 8672099 = 8672208
  • 227 + 8671981 = 8672208
  • 229 + 8671979 = 8672208

Showing the first eight; more decompositions exist.
