Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163844, here are decompositions:

  • 3 + 163841 = 163844
  • 73 + 163771 = 163844
  • 103 + 163741 = 163844
  • 211 + 163633 = 163844
  • 223 + 163621 = 163844
  • 271 + 163573 = 163844
  • 277 + 163567 = 163844
  • 283 + 163561 = 163844

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 163,844 and was likely granted around 1874.

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