Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166604, here are decompositions:

  • 3 + 166601 = 166604
  • 7 + 166597 = 166604
  • 37 + 166567 = 166604
  • 43 + 166561 = 166604
  • 211 + 166393 = 166604
  • 241 + 166363 = 166604
  • 307 + 166297 = 166604
  • 331 + 166273 = 166604

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 166,604 and was likely granted around 1874.

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