Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513626, here are decompositions:
- 97 + 513529 = 513626
- 199 + 513427 = 513626
- 229 + 513397 = 513626
- 307 + 513319 = 513626
- 313 + 513313 = 513626
- 349 + 513277 = 513626
- 457 + 513169 = 513626
- 523 + 513103 = 513626
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 513,626 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 513626 first appears in π at position 266,066 of the decimal expansion (the 266,066ordinal-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.
