Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178204, here are decompositions:
- 17 + 178187 = 178204
- 53 + 178151 = 178204
- 101 + 178103 = 178204
- 113 + 178091 = 178204
- 137 + 178067 = 178204
- 167 + 178037 = 178204
- 251 + 177953 = 178204
- 311 + 177893 = 178204
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 178,204 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 178204 first appears in π at position 181,238 of the decimal expansion (the 181,238ordinal-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.
