Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158078, here are decompositions:
- 7 + 158071 = 158078
- 31 + 158047 = 158078
- 61 + 158017 = 158078
- 79 + 157999 = 158078
- 127 + 157951 = 158078
- 181 + 157897 = 158078
- 211 + 157867 = 158078
- 241 + 157837 = 158078
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 158,078 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
