Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166874, here are decompositions:

  • 3 + 166871 = 166874
  • 7 + 166867 = 166874
  • 13 + 166861 = 166874
  • 31 + 166843 = 166874
  • 67 + 166807 = 166874
  • 151 + 166723 = 166874
  • 181 + 166693 = 166874
  • 271 + 166603 = 166874

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 166,874 and was likely granted around 1874.

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