Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173864, here are decompositions:
- 3 + 173861 = 173864
- 13 + 173851 = 173864
- 37 + 173827 = 173864
- 151 + 173713 = 173864
- 157 + 173707 = 173864
- 181 + 173683 = 173864
- 193 + 173671 = 173864
- 367 + 173497 = 173864
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 173,864 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 173864 first appears in π at position 80,952 of the decimal expansion (the 80,952ordinal-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.
