Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666880, here are decompositions:

  • 17 + 8666863 = 8666880
  • 31 + 8666849 = 8666880
  • 41 + 8666839 = 8666880
  • 71 + 8666809 = 8666880
  • 73 + 8666807 = 8666880
  • 83 + 8666797 = 8666880
  • 97 + 8666783 = 8666880
  • 107 + 8666773 = 8666880

Showing the first eight; more decompositions exist.
