Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705320, here are decompositions:

  • 23 + 8705297 = 8705320
  • 59 + 8705261 = 8705320
  • 83 + 8705237 = 8705320
  • 101 + 8705219 = 8705320
  • 137 + 8705183 = 8705320
  • 149 + 8705171 = 8705320
  • 227 + 8705093 = 8705320
  • 233 + 8705087 = 8705320

Showing the first eight; more decompositions exist.
