Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513136, here are decompositions:
- 5 + 513131 = 513136
- 53 + 513083 = 513136
- 83 + 513053 = 513136
- 89 + 513047 = 513136
- 137 + 512999 = 513136
- 233 + 512903 = 513136
- 293 + 512843 = 513136
- 317 + 512819 = 513136
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 513,136 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 513136 first appears in π at position 168,686 of the decimal expansion (the 168,686ordinal-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.
