Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82478, here are decompositions:

  • 7 + 82471 = 82478
  • 127 + 82351 = 82478
  • 139 + 82339 = 82478
  • 199 + 82279 = 82478
  • 211 + 82267 = 82478
  • 241 + 82237 = 82478
  • 271 + 82207 = 82478
  • 307 + 82171 = 82478

Showing the first eight; more decompositions exist.
