Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513774, here are decompositions:
- 5 + 513769 = 513774
- 7 + 513767 = 513774
- 13 + 513761 = 513774
- 43 + 513731 = 513774
- 47 + 513727 = 513774
- 83 + 513691 = 513774
- 101 + 513673 = 513774
- 181 + 513593 = 513774
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 513,774 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 513774 first appears in π at position 186,446 of the decimal expansion (the 186,446ordinal-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.
