Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104542, here are decompositions:
- 5 + 104537 = 104542
- 29 + 104513 = 104542
- 71 + 104471 = 104542
- 83 + 104459 = 104542
- 149 + 104393 = 104542
- 173 + 104369 = 104542
- 233 + 104309 = 104542
- 311 + 104231 = 104542
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 104,542 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 104542 first appears in π at position 514,191 of the decimal expansion (the 514,191ordinal-suffix:st 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.
