Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166612, here are decompositions:

  • 3 + 166609 = 166612
  • 11 + 166601 = 166612
  • 41 + 166571 = 166612
  • 71 + 166541 = 166612
  • 263 + 166349 = 166612
  • 293 + 166319 = 166612
  • 311 + 166301 = 166612
  • 353 + 166259 = 166612

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 166,612 and was likely granted around 1874.

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