Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173400, here are decompositions:
- 41 + 173359 = 173400
- 43 + 173357 = 173400
- 53 + 173347 = 173400
- 103 + 173297 = 173400
- 107 + 173293 = 173400
- 109 + 173291 = 173400
- 127 + 173273 = 173400
- 137 + 173263 = 173400
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 173,400 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 173400 first appears in π at position 97,410 of the decimal expansion (the 97,410ordinal-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.
