Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163802, here are decompositions:

  • 13 + 163789 = 163802
  • 31 + 163771 = 163802
  • 61 + 163741 = 163802
  • 73 + 163729 = 163802
  • 181 + 163621 = 163802
  • 229 + 163573 = 163802
  • 241 + 163561 = 163802
  • 409 + 163393 = 163802

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 163,802 and was likely granted around 1874.

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