Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177644, here are decompositions:
- 43 + 177601 = 177644
- 151 + 177493 = 177644
- 157 + 177487 = 177644
- 163 + 177481 = 177644
- 211 + 177433 = 177644
- 223 + 177421 = 177644
- 307 + 177337 = 177644
- 421 + 177223 = 177644
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 177,644 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 177644 first appears in π at position 405,365 of the decimal expansion (the 405,365ordinal-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.
