Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135900, here are decompositions:
- 7 + 135893 = 135900
- 13 + 135887 = 135900
- 41 + 135859 = 135900
- 59 + 135841 = 135900
- 71 + 135829 = 135900
- 101 + 135799 = 135900
- 113 + 135787 = 135900
- 157 + 135743 = 135900
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 135,900 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
