Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661208, here are decompositions:

  • 5 + 8661203 = 8661208
  • 11 + 8661197 = 8661208
  • 47 + 8661161 = 8661208
  • 71 + 8661137 = 8661208
  • 89 + 8661119 = 8661208
  • 239 + 8660969 = 8661208
  • 317 + 8660891 = 8661208
  • 389 + 8660819 = 8661208

Showing the first eight; more decompositions exist.
