Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165814, here are decompositions:

  • 3 + 165811 = 165814
  • 101 + 165713 = 165814
  • 107 + 165707 = 165814
  • 113 + 165701 = 165814
  • 197 + 165617 = 165814
  • 227 + 165587 = 165814
  • 263 + 165551 = 165814
  • 281 + 165533 = 165814

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 165,814 and was likely granted around 1874.

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