Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713128, here are decompositions:

  • 5 + 8713123 = 8713128
  • 7 + 8713121 = 8713128
  • 19 + 8713109 = 8713128
  • 41 + 8713087 = 8713128
  • 59 + 8713069 = 8713128
  • 131 + 8712997 = 8713128
  • 197 + 8712931 = 8713128
  • 269 + 8712859 = 8713128

Showing the first eight; more decompositions exist.
