Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513126, here are decompositions:
- 17 + 513109 = 513126
- 23 + 513103 = 513126
- 43 + 513083 = 513126
- 59 + 513067 = 513126
- 67 + 513059 = 513126
- 73 + 513053 = 513126
- 79 + 513047 = 513126
- 109 + 513017 = 513126
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 513,126 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 513126 first appears in π at position 320,343 of the decimal expansion (the 320,343ordinal-suffix:rd 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.
