Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513506, here are decompositions:
- 67 + 513439 = 513506
- 79 + 513427 = 513506
- 109 + 513397 = 513506
- 139 + 513367 = 513506
- 193 + 513313 = 513506
- 199 + 513307 = 513506
- 223 + 513283 = 513506
- 229 + 513277 = 513506
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 513,506 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 513506 first appears in π at position 852,552 of the decimal expansion (the 852,552ordinal-suffix:nd 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.
