Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163874, here are decompositions:

  • 3 + 163871 = 163874
  • 13 + 163861 = 163874
  • 103 + 163771 = 163874
  • 241 + 163633 = 163874
  • 307 + 163567 = 163874
  • 313 + 163561 = 163874
  • 331 + 163543 = 163874
  • 397 + 163477 = 163874

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 163,874 and was likely granted around 1874.

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