Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163418, here are decompositions:

  • 7 + 163411 = 163418
  • 67 + 163351 = 163418
  • 97 + 163321 = 163418
  • 109 + 163309 = 163418
  • 271 + 163147 = 163418
  • 397 + 163021 = 163418
  • 421 + 162997 = 163418
  • 571 + 162847 = 163418

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 163,418 and was likely granted around 1874.

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