Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513916, here are decompositions:
- 17 + 513899 = 513916
- 149 + 513767 = 513916
- 167 + 513749 = 513916
- 197 + 513719 = 513916
- 233 + 513683 = 513916
- 383 + 513533 = 513916
- 443 + 513473 = 513916
- 509 + 513407 = 513916
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 513,916 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 513916 first appears in π at position 124,716 of the decimal expansion (the 124,716ordinal-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.
