Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712160, here are decompositions:

  • 3 + 8712157 = 8712160
  • 11 + 8712149 = 8712160
  • 47 + 8712113 = 8712160
  • 101 + 8712059 = 8712160
  • 131 + 8712029 = 8712160
  • 173 + 8711987 = 8712160
  • 227 + 8711933 = 8712160
  • 239 + 8711921 = 8712160

Showing the first eight; more decompositions exist.
