Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625312, here are decompositions:

  • 11 + 8625301 = 8625312
  • 23 + 8625289 = 8625312
  • 79 + 8625233 = 8625312
  • 83 + 8625229 = 8625312
  • 109 + 8625203 = 8625312
  • 139 + 8625173 = 8625312
  • 181 + 8625131 = 8625312
  • 191 + 8625121 = 8625312

Showing the first eight; more decompositions exist.
