Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513502, here are decompositions:
- 23 + 513479 = 513502
- 29 + 513473 = 513502
- 71 + 513431 = 513502
- 83 + 513419 = 513502
- 131 + 513371 = 513502
- 149 + 513353 = 513502
- 191 + 513311 = 513502
- 233 + 513269 = 513502
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 513,502 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 513502 first appears in π at position 445,587 of the decimal expansion (the 445,587ordinal-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.
