Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166410, here are decompositions:

  • 7 + 166403 = 166410
  • 11 + 166399 = 166410
  • 17 + 166393 = 166410
  • 47 + 166363 = 166410
  • 53 + 166357 = 166410
  • 59 + 166351 = 166410
  • 61 + 166349 = 166410
  • 107 + 166303 = 166410

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 166,410 and was likely granted around 1874.

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