Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513874, here are decompositions:
- 3 + 513871 = 513874
- 107 + 513767 = 513874
- 113 + 513761 = 513874
- 191 + 513683 = 513874
- 233 + 513641 = 513874
- 281 + 513593 = 513874
- 401 + 513473 = 513874
- 443 + 513431 = 513874
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 513,874 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 513874 first appears in π at position 377,016 of the decimal expansion (the 377,016ordinal-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.
