Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182188, here are decompositions:

  • 11 + 182177 = 182188
  • 29 + 182159 = 182188
  • 47 + 182141 = 182188
  • 59 + 182129 = 182188
  • 89 + 182099 = 182188
  • 131 + 182057 = 182188
  • 179 + 182009 = 182188
  • 191 + 181997 = 182188

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 182,188 and was likely granted around 1875.

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