Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755872, here are decompositions:

  • 19 + 8755853 = 8755872
  • 23 + 8755849 = 8755872
  • 31 + 8755841 = 8755872
  • 53 + 8755819 = 8755872
  • 61 + 8755811 = 8755872
  • 131 + 8755741 = 8755872
  • 149 + 8755723 = 8755872
  • 173 + 8755699 = 8755872

Showing the first eight; more decompositions exist.
