Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684040, here are decompositions:

  • 11 + 8684029 = 8684040
  • 17 + 8684023 = 8684040
  • 31 + 8684009 = 8684040
  • 37 + 8684003 = 8684040
  • 97 + 8683943 = 8684040
  • 107 + 8683933 = 8684040
  • 163 + 8683877 = 8684040
  • 257 + 8683783 = 8684040

Showing the first eight; more decompositions exist.
