Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180764, here are decompositions:
- 13 + 180751 = 180764
- 97 + 180667 = 180764
- 223 + 180541 = 180764
- 373 + 180391 = 180764
- 433 + 180331 = 180764
- 457 + 180307 = 180764
- 523 + 180241 = 180764
- 691 + 180073 = 180764
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 180,764 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 180764 first appears in π at position 527,838 of the decimal expansion (the 527,838ordinal-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.
