Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102772, here are decompositions:

  • 3 + 102769 = 102772
  • 11 + 102761 = 102772
  • 71 + 102701 = 102772
  • 179 + 102593 = 102772
  • 233 + 102539 = 102772
  • 239 + 102533 = 102772
  • 269 + 102503 = 102772
  • 311 + 102461 = 102772

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 102,772 and was likely granted around 1870.

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