Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513784, here are decompositions:
- 3 + 513781 = 513784
- 17 + 513767 = 513784
- 23 + 513761 = 513784
- 53 + 513731 = 513784
- 101 + 513683 = 513784
- 191 + 513593 = 513784
- 251 + 513533 = 513784
- 311 + 513473 = 513784
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 513,784 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 513784 first appears in π at position 392,431 of the decimal expansion (the 392,431ordinal-suffix:st 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.
