Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158342, here are decompositions:
- 13 + 158329 = 158342
- 73 + 158269 = 158342
- 109 + 158233 = 158342
- 181 + 158161 = 158342
- 199 + 158143 = 158342
- 229 + 158113 = 158342
- 271 + 158071 = 158342
- 313 + 158029 = 158342
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 158,342 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 158342 first appears in π at position 16,842 of the decimal expansion (the 16,842ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
