Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745040, here are decompositions:

  • 23 + 8745017 = 8745040
  • 71 + 8744969 = 8745040
  • 89 + 8744951 = 8745040
  • 113 + 8744927 = 8745040
  • 131 + 8744909 = 8745040
  • 137 + 8744903 = 8745040
  • 149 + 8744891 = 8745040
  • 179 + 8744861 = 8745040

Showing the first eight; more decompositions exist.
