Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709210, here are decompositions:

  • 19 + 8709191 = 8709210
  • 23 + 8709187 = 8709210
  • 61 + 8709149 = 8709210
  • 71 + 8709139 = 8709210
  • 89 + 8709121 = 8709210
  • 131 + 8709079 = 8709210
  • 151 + 8709059 = 8709210
  • 239 + 8708971 = 8709210

Showing the first eight; more decompositions exist.
