Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166210, here are decompositions:

  • 3 + 166207 = 166210
  • 41 + 166169 = 166210
  • 53 + 166157 = 166210
  • 59 + 166151 = 166210
  • 167 + 166043 = 166210
  • 179 + 166031 = 166210
  • 197 + 166013 = 166210
  • 227 + 165983 = 166210

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 166,210 and was likely granted around 1874.

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