Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164288, here are decompositions:

  • 37 + 164251 = 164288
  • 79 + 164209 = 164288
  • 97 + 164191 = 164288
  • 139 + 164149 = 164288
  • 199 + 164089 = 164288
  • 277 + 164011 = 164288
  • 307 + 163981 = 164288
  • 379 + 163909 = 164288

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 164,288 and was likely granted around 1874.

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