Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135424, here are decompositions:
- 71 + 135353 = 135424
- 167 + 135257 = 135424
- 227 + 135197 = 135424
- 251 + 135173 = 135424
- 293 + 135131 = 135424
- 347 + 135077 = 135424
- 503 + 134921 = 135424
- 557 + 134867 = 135424
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 135,424 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 135424 first appears in π at position 252,839 of the decimal expansion (the 252,839ordinal-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.
