Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158804, here are decompositions:
- 13 + 158791 = 158804
- 43 + 158761 = 158804
- 73 + 158731 = 158804
- 157 + 158647 = 158804
- 193 + 158611 = 158804
- 223 + 158581 = 158804
- 241 + 158563 = 158804
- 277 + 158527 = 158804
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 158,804 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 158804 first appears in π at position 360,266 of the decimal expansion (the 360,266ordinal-suffix:th 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.
