Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513124, here are decompositions:
- 23 + 513101 = 513124
- 41 + 513083 = 513124
- 71 + 513053 = 513124
- 83 + 513041 = 513124
- 107 + 513017 = 513124
- 197 + 512927 = 513124
- 233 + 512891 = 513124
- 281 + 512843 = 513124
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 513,124 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 513124 first appears in π at position 160,051 of the decimal expansion (the 160,051ordinal-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.
