Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513252, here are decompositions:
- 13 + 513239 = 513252
- 79 + 513173 = 513252
- 83 + 513169 = 513252
- 149 + 513103 = 513252
- 151 + 513101 = 513252
- 193 + 513059 = 513252
- 199 + 513053 = 513252
- 211 + 513041 = 513252
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 513,252 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 513252 first appears in π at position 91,624 of the decimal expansion (the 91,624ordinal-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.
