Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108172, here are decompositions:
- 11 + 108161 = 108172
- 41 + 108131 = 108172
- 83 + 108089 = 108172
- 131 + 108041 = 108172
- 149 + 108023 = 108172
- 173 + 107999 = 108172
- 191 + 107981 = 108172
- 269 + 107903 = 108172
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 108,172 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 108172 first appears in π at position 243,632 of the decimal expansion (the 243,632ordinal-suffix:nd 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.
