Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166474, here are decompositions:

  • 3 + 166471 = 166474
  • 17 + 166457 = 166474
  • 71 + 166403 = 166474
  • 173 + 166301 = 166474
  • 227 + 166247 = 166474
  • 317 + 166157 = 166474
  • 431 + 166043 = 166474
  • 443 + 166031 = 166474

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 166,474 and was likely granted around 1874.

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