Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513636, here are decompositions:
- 5 + 513631 = 513636
- 43 + 513593 = 513636
- 103 + 513533 = 513636
- 107 + 513529 = 513636
- 127 + 513509 = 513636
- 157 + 513479 = 513636
- 163 + 513473 = 513636
- 197 + 513439 = 513636
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 513,636 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 513636 first appears in π at position 178,461 of the decimal expansion (the 178,461ordinal-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.
