Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725418, here are decompositions:

  • 19 + 8725399 = 8725418
  • 61 + 8725357 = 8725418
  • 139 + 8725279 = 8725418
  • 199 + 8725219 = 8725418
  • 211 + 8725207 = 8725418
  • 241 + 8725177 = 8725418
  • 271 + 8725147 = 8725418
  • 277 + 8725141 = 8725418

Showing the first eight; more decompositions exist.
