Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135142, here are decompositions:
- 11 + 135131 = 135142
- 23 + 135119 = 135142
- 41 + 135101 = 135142
- 53 + 135089 = 135142
- 83 + 135059 = 135142
- 113 + 135029 = 135142
- 191 + 134951 = 135142
- 233 + 134909 = 135142
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 135,142 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 135142 first appears in π at position 43,285 of the decimal expansion (the 43,285ordinal-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.
