Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172582, here are decompositions:

  • 29 + 172553 = 172582
  • 41 + 172541 = 172582
  • 149 + 172433 = 172582
  • 239 + 172343 = 172582
  • 251 + 172331 = 172582
  • 269 + 172313 = 172582
  • 359 + 172223 = 172582
  • 383 + 172199 = 172582

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 172,582 and was likely granted around 1874.

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