Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108438, here are decompositions:
- 17 + 108421 = 108438
- 37 + 108401 = 108438
- 59 + 108379 = 108438
- 61 + 108377 = 108438
- 79 + 108359 = 108438
- 137 + 108301 = 108438
- 149 + 108289 = 108438
- 151 + 108287 = 108438
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 108,438 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 108438 first appears in π at position 28,488 of the decimal expansion (the 28,488ordinal-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.
