Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162436, here are decompositions:

  • 17 + 162419 = 162436
  • 23 + 162413 = 162436
  • 47 + 162389 = 162436
  • 149 + 162287 = 162436
  • 167 + 162269 = 162436
  • 173 + 162263 = 162436
  • 179 + 162257 = 162436
  • 227 + 162209 = 162436

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 162,436 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
