Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108542, here are decompositions:
- 13 + 108529 = 108542
- 43 + 108499 = 108542
- 79 + 108463 = 108542
- 103 + 108439 = 108542
- 163 + 108379 = 108542
- 199 + 108343 = 108542
- 241 + 108301 = 108542
- 271 + 108271 = 108542
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 108,542 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 108542 first appears in π at position 255,198 of the decimal expansion (the 255,198ordinal-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.
