Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166930, here are decompositions:

  • 11 + 166919 = 166930
  • 59 + 166871 = 166930
  • 83 + 166847 = 166930
  • 89 + 166841 = 166930
  • 107 + 166823 = 166930
  • 131 + 166799 = 166930
  • 149 + 166781 = 166930
  • 191 + 166739 = 166930

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 166,930 and was likely granted around 1874.

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