Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513238, here are decompositions:
- 71 + 513167 = 513238
- 101 + 513137 = 513238
- 107 + 513131 = 513238
- 137 + 513101 = 513238
- 179 + 513059 = 513238
- 191 + 513047 = 513238
- 197 + 513041 = 513238
- 239 + 512999 = 513238
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 513,238 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 513238 first appears in π at position 686,861 of the decimal expansion (the 686,861ordinal-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.
