Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513458, here are decompositions:
- 19 + 513439 = 513458
- 31 + 513427 = 513458
- 61 + 513397 = 513458
- 139 + 513319 = 513458
- 151 + 513307 = 513458
- 181 + 513277 = 513458
- 349 + 513109 = 513458
- 457 + 513001 = 513458
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 513,458 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 513458 first appears in π at position 856,164 of the decimal expansion (the 856,164ordinal-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.
