Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158132, here are decompositions:
- 3 + 158129 = 158132
- 19 + 158113 = 158132
- 61 + 158071 = 158132
- 103 + 158029 = 158132
- 181 + 157951 = 158132
- 199 + 157933 = 158132
- 463 + 157669 = 158132
- 571 + 157561 = 158132
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 158,132 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
