Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178104, here are decompositions:
- 11 + 178093 = 178104
- 13 + 178091 = 178104
- 37 + 178067 = 178104
- 67 + 178037 = 178104
- 83 + 178021 = 178104
- 103 + 178001 = 178104
- 137 + 177967 = 178104
- 151 + 177953 = 178104
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 178,104 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 178104 first appears in π at position 886,034 of the decimal expansion (the 886,034ordinal-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.
