Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513588, here are decompositions:
- 59 + 513529 = 513588
- 79 + 513509 = 513588
- 107 + 513481 = 513588
- 109 + 513479 = 513588
- 149 + 513439 = 513588
- 157 + 513431 = 513588
- 181 + 513407 = 513588
- 191 + 513397 = 513588
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 513,588 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 513588 first appears in π at position 67,104 of the decimal expansion (the 67,104ordinal-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.
