Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513266, here are decompositions:
- 97 + 513169 = 513266
- 109 + 513157 = 513266
- 157 + 513109 = 513266
- 163 + 513103 = 513266
- 199 + 513067 = 513266
- 277 + 512989 = 513266
- 307 + 512959 = 513266
- 337 + 512929 = 513266
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 513,266 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 513266 first appears in π at position 656,592 of the decimal expansion (the 656,592ordinal-suffix:nd 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.
