Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644188, here are decompositions:

  • 17 + 8644171 = 8644188
  • 31 + 8644157 = 8644188
  • 41 + 8644147 = 8644188
  • 97 + 8644091 = 8644188
  • 107 + 8644081 = 8644188
  • 127 + 8644061 = 8644188
  • 131 + 8644057 = 8644188
  • 139 + 8644049 = 8644188

Showing the first eight; more decompositions exist.
