Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177564, here are decompositions:
- 11 + 177553 = 177564
- 31 + 177533 = 177564
- 53 + 177511 = 177564
- 71 + 177493 = 177564
- 83 + 177481 = 177564
- 97 + 177467 = 177564
- 131 + 177433 = 177564
- 137 + 177427 = 177564
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 177,564 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 177564 first appears in π at position 184,559 of the decimal expansion (the 184,559ordinal-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.
