Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168364, here are decompositions:
- 11 + 168353 = 168364
- 17 + 168347 = 168364
- 41 + 168323 = 168364
- 71 + 168293 = 168364
- 83 + 168281 = 168364
- 101 + 168263 = 168364
- 137 + 168227 = 168364
- 167 + 168197 = 168364
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 168,364 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 168364 first appears in π at position 305,989 of the decimal expansion (the 305,989ordinal-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.
