Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178804, here are decompositions:
- 5 + 178799 = 178804
- 11 + 178793 = 178804
- 23 + 178781 = 178804
- 47 + 178757 = 178804
- 107 + 178697 = 178804
- 113 + 178691 = 178804
- 191 + 178613 = 178804
- 233 + 178571 = 178804
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 178,804 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 178804 first appears in π at position 304,633 of the decimal expansion (the 304,633ordinal-suffix:rd 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.
