Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715972, here are decompositions:

  • 11 + 8715961 = 8715972
  • 71 + 8715901 = 8715972
  • 131 + 8715841 = 8715972
  • 179 + 8715793 = 8715972
  • 193 + 8715779 = 8715972
  • 211 + 8715761 = 8715972
  • 241 + 8715731 = 8715972
  • 263 + 8715709 = 8715972

Showing the first eight; more decompositions exist.
