Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513324, here are decompositions:
- 5 + 513319 = 513324
- 11 + 513313 = 513324
- 13 + 513311 = 513324
- 17 + 513307 = 513324
- 41 + 513283 = 513324
- 47 + 513277 = 513324
- 67 + 513257 = 513324
- 151 + 513173 = 513324
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 513,324 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 513324 first appears in π at position 522,141 of the decimal expansion (the 522,141ordinal-suffix:st 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.
