Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513824, here are decompositions:
- 43 + 513781 = 513824
- 97 + 513727 = 513824
- 127 + 513697 = 513824
- 151 + 513673 = 513824
- 193 + 513631 = 513824
- 313 + 513511 = 513824
- 397 + 513427 = 513824
- 457 + 513367 = 513824
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 513,824 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 513824 first appears in π at position 267,913 of the decimal expansion (the 267,913ordinal-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.
