Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165628, here are decompositions:

  • 11 + 165617 = 165628
  • 17 + 165611 = 165628
  • 41 + 165587 = 165628
  • 59 + 165569 = 165628
  • 101 + 165527 = 165628
  • 149 + 165479 = 165628
  • 179 + 165449 = 165628
  • 191 + 165437 = 165628

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 165,628 and was likely granted around 1874.

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