Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513580, here are decompositions:
- 47 + 513533 = 513580
- 71 + 513509 = 513580
- 101 + 513479 = 513580
- 107 + 513473 = 513580
- 149 + 513431 = 513580
- 173 + 513407 = 513580
- 227 + 513353 = 513580
- 233 + 513347 = 513580
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 513,580 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 513580 first appears in π at position 542,451 of the decimal expansion (the 542,451ordinal-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.
