Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173424, here are decompositions:
- 67 + 173357 = 173424
- 127 + 173297 = 173424
- 131 + 173293 = 173424
- 151 + 173273 = 173424
- 157 + 173267 = 173424
- 233 + 173191 = 173424
- 241 + 173183 = 173424
- 283 + 173141 = 173424
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 173,424 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 173424 first appears in π at position 164,840 of the decimal expansion (the 164,840ordinal-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.
