Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513536, here are decompositions:
- 3 + 513533 = 513536
- 7 + 513529 = 513536
- 97 + 513439 = 513536
- 109 + 513427 = 513536
- 139 + 513397 = 513536
- 223 + 513313 = 513536
- 229 + 513307 = 513536
- 367 + 513169 = 513536
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 513,536 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 513536 first appears in π at position 29,783 of the decimal expansion (the 29,783ordinal-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.
