Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561764, here are decompositions:
- 3 + 561761 = 561764
- 31 + 561733 = 561764
- 61 + 561703 = 561764
- 97 + 561667 = 561764
- 157 + 561607 = 561764
- 211 + 561553 = 561764
- 397 + 561367 = 561764
- 421 + 561343 = 561764
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 561,764 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 561764 first appears in π at position 756,853 of the decimal expansion (the 756,853ordinal-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.
