Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178764, here are decompositions:
- 7 + 178757 = 178764
- 11 + 178753 = 178764
- 67 + 178697 = 178764
- 71 + 178693 = 178764
- 73 + 178691 = 178764
- 83 + 178681 = 178764
- 137 + 178627 = 178764
- 151 + 178613 = 178764
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 178,764 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 178764 first appears in π at position 63,258 of the decimal expansion (the 63,258ordinal-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.
