Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173664, here are decompositions:
- 5 + 173659 = 173664
- 13 + 173651 = 173664
- 17 + 173647 = 173664
- 47 + 173617 = 173664
- 103 + 173561 = 173664
- 163 + 173501 = 173664
- 167 + 173497 = 173664
- 173 + 173491 = 173664
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 173,664 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 173664 first appears in π at position 361,572 of the decimal expansion (the 361,572ordinal-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.
