Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168304, here are decompositions:
- 11 + 168293 = 168304
- 23 + 168281 = 168304
- 41 + 168263 = 168304
- 107 + 168197 = 168304
- 233 + 168071 = 168304
- 281 + 168023 = 168304
- 317 + 167987 = 168304
- 431 + 167873 = 168304
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 168,304 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 168304 first appears in π at position 823,547 of the decimal expansion (the 823,547ordinal-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.
