Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715210, here are decompositions:

  • 17 + 8715193 = 8715210
  • 19 + 8715191 = 8715210
  • 29 + 8715181 = 8715210
  • 59 + 8715151 = 8715210
  • 67 + 8715143 = 8715210
  • 103 + 8715107 = 8715210
  • 107 + 8715103 = 8715210
  • 131 + 8715079 = 8715210

Showing the first eight; more decompositions exist.
