Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656168, here are decompositions:

  • 5 + 8656163 = 8656168
  • 71 + 8656097 = 8656168
  • 89 + 8656079 = 8656168
  • 137 + 8656031 = 8656168
  • 149 + 8656019 = 8656168
  • 251 + 8655917 = 8656168
  • 359 + 8655809 = 8656168
  • 419 + 8655749 = 8656168

Showing the first eight; more decompositions exist.
