Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106172, here are decompositions:
- 43 + 106129 = 106172
- 139 + 106033 = 106172
- 229 + 105943 = 106172
- 421 + 105751 = 106172
- 439 + 105733 = 106172
- 499 + 105673 = 106172
- 523 + 105649 = 106172
- 571 + 105601 = 106172
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 106,172 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 106172 first appears in π at position 367,686 of the decimal expansion (the 367,686ordinal-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.
