Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178446, here are decompositions:
- 5 + 178441 = 178446
- 7 + 178439 = 178446
- 29 + 178417 = 178446
- 43 + 178403 = 178446
- 53 + 178393 = 178446
- 97 + 178349 = 178446
- 113 + 178333 = 178446
- 139 + 178307 = 178446
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 178,446 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 178446 first appears in π at position 299,424 of the decimal expansion (the 299,424ordinal-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.
