Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178746, here are decompositions:
- 53 + 178693 = 178746
- 103 + 178643 = 178746
- 107 + 178639 = 178746
- 137 + 178609 = 178746
- 149 + 178597 = 178746
- 179 + 178567 = 178746
- 233 + 178513 = 178746
- 257 + 178489 = 178746
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 178,746 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 178746 first appears in π at position 887,933 of the decimal expansion (the 887,933ordinal-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.
