Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668192, here are decompositions:

  • 41 + 8668151 = 8668192
  • 59 + 8668133 = 8668192
  • 131 + 8668061 = 8668192
  • 149 + 8668043 = 8668192
  • 191 + 8668001 = 8668192
  • 263 + 8667929 = 8668192
  • 293 + 8667899 = 8668192
  • 383 + 8667809 = 8668192

Showing the first eight; more decompositions exist.
