Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158126, here are decompositions:
- 13 + 158113 = 158126
- 79 + 158047 = 158126
- 97 + 158029 = 158126
- 109 + 158017 = 158126
- 127 + 157999 = 158126
- 193 + 157933 = 158126
- 229 + 157897 = 158126
- 313 + 157813 = 158126
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 158,126 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
