Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188136, here are decompositions:

  • 29 + 188107 = 188136
  • 107 + 188029 = 188136
  • 149 + 187987 = 188136
  • 163 + 187973 = 188136
  • 173 + 187963 = 188136
  • 227 + 187909 = 188136
  • 229 + 187907 = 188136
  • 239 + 187897 = 188136

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 188,136 and was likely granted around 1875.

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