Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755866, here are decompositions:

  • 13 + 8755853 = 8755866
  • 17 + 8755849 = 8755866
  • 43 + 8755823 = 8755866
  • 47 + 8755819 = 8755866
  • 137 + 8755729 = 8755866
  • 167 + 8755699 = 8755866
  • 199 + 8755667 = 8755866
  • 227 + 8755639 = 8755866

Showing the first eight; more decompositions exist.
