Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177664, here are decompositions:
- 17 + 177647 = 177664
- 41 + 177623 = 177664
- 131 + 177533 = 177664
- 191 + 177473 = 177664
- 197 + 177467 = 177664
- 233 + 177431 = 177664
- 281 + 177383 = 177664
- 317 + 177347 = 177664
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 177,664 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 177664 first appears in π at position 164,971 of the decimal expansion (the 164,971ordinal-suffix:st 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.
