Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136220, here are decompositions:
- 3 + 136217 = 136220
- 13 + 136207 = 136220
- 31 + 136189 = 136220
- 43 + 136177 = 136220
- 109 + 136111 = 136220
- 127 + 136093 = 136220
- 151 + 136069 = 136220
- 163 + 136057 = 136220
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 136,220 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
