Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165270, here are decompositions:

  • 23 + 165247 = 165270
  • 37 + 165233 = 165270
  • 41 + 165229 = 165270
  • 59 + 165211 = 165270
  • 67 + 165203 = 165270
  • 89 + 165181 = 165270
  • 97 + 165173 = 165270
  • 109 + 165161 = 165270

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 165,270 and was likely granted around 1874.

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