Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717142, here are decompositions:

  • 11 + 8717131 = 8717142
  • 19 + 8717123 = 8717142
  • 23 + 8717119 = 8717142
  • 29 + 8717113 = 8717142
  • 101 + 8717041 = 8717142
  • 131 + 8717011 = 8717142
  • 199 + 8716943 = 8717142
  • 223 + 8716919 = 8717142

Showing the first eight; more decompositions exist.
