Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511342, here are decompositions:
- 5 + 511337 = 511342
- 53 + 511289 = 511342
- 131 + 511211 = 511342
- 149 + 511193 = 511342
- 173 + 511169 = 511342
- 179 + 511163 = 511342
- 191 + 511151 = 511342
- 233 + 511109 = 511342
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 511,342 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 511342 first appears in π at position 961,399 of the decimal expansion (the 961,399ordinal-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.
