Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639160, here are decompositions:

  • 7 + 8639153 = 8639160
  • 11 + 8639149 = 8639160
  • 17 + 8639143 = 8639160
  • 29 + 8639131 = 8639160
  • 37 + 8639123 = 8639160
  • 41 + 8639119 = 8639160
  • 53 + 8639107 = 8639160
  • 71 + 8639089 = 8639160

Showing the first eight; more decompositions exist.
