Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158424, here are decompositions:
- 5 + 158419 = 158424
- 17 + 158407 = 158424
- 31 + 158393 = 158424
- 53 + 158371 = 158424
- 61 + 158363 = 158424
- 67 + 158357 = 158424
- 73 + 158351 = 158424
- 83 + 158341 = 158424
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 158,424 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 158424 first appears in π at position 389,910 of the decimal expansion (the 389,910ordinal-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.
