Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705210, here are decompositions:

  • 43 + 8705167 = 8705210
  • 61 + 8705149 = 8705210
  • 181 + 8705029 = 8705210
  • 229 + 8704981 = 8705210
  • 307 + 8704903 = 8705210
  • 313 + 8704897 = 8705210
  • 373 + 8704837 = 8705210
  • 433 + 8704777 = 8705210

Showing the first eight; more decompositions exist.
