Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513904, here are decompositions:
- 5 + 513899 = 513904
- 23 + 513881 = 513904
- 137 + 513767 = 513904
- 173 + 513731 = 513904
- 263 + 513641 = 513904
- 311 + 513593 = 513904
- 431 + 513473 = 513904
- 557 + 513347 = 513904
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 513,904 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 513904 first appears in π at position 608,736 of the decimal expansion (the 608,736ordinal-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.
