Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513478, here are decompositions:
- 5 + 513473 = 513478
- 47 + 513431 = 513478
- 59 + 513419 = 513478
- 71 + 513407 = 513478
- 107 + 513371 = 513478
- 131 + 513347 = 513478
- 137 + 513341 = 513478
- 167 + 513311 = 513478
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 513,478 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 513478 first appears in π at position 289,485 of the decimal expansion (the 289,485ordinal-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.
