Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108538, here are decompositions:
- 5 + 108533 = 108538
- 41 + 108497 = 108538
- 137 + 108401 = 108538
- 179 + 108359 = 108538
- 191 + 108347 = 108538
- 251 + 108287 = 108538
- 347 + 108191 = 108538
- 359 + 108179 = 108538
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 108,538 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 108538 first appears in π at position 293,239 of the decimal expansion (the 293,239ordinal-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.
