Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163658, here are decompositions:

  • 31 + 163627 = 163658
  • 37 + 163621 = 163658
  • 97 + 163561 = 163658
  • 181 + 163477 = 163658
  • 241 + 163417 = 163658
  • 307 + 163351 = 163658
  • 331 + 163327 = 163658
  • 337 + 163321 = 163658

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 163,658 and was likely granted around 1874.

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