Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715180, here are decompositions:

  • 29 + 8715151 = 8715180
  • 37 + 8715143 = 8715180
  • 73 + 8715107 = 8715180
  • 101 + 8715079 = 8715180
  • 139 + 8715041 = 8715180
  • 151 + 8715029 = 8715180
  • 157 + 8715023 = 8715180
  • 167 + 8715013 = 8715180

Showing the first eight; more decompositions exist.
