Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136142, here are decompositions:
- 3 + 136139 = 136142
- 31 + 136111 = 136142
- 43 + 136099 = 136142
- 73 + 136069 = 136142
- 109 + 136033 = 136142
- 163 + 135979 = 136142
- 229 + 135913 = 136142
- 283 + 135859 = 136142
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 136,142 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 136142 first appears in π at position 183,046 of the decimal expansion (the 183,046ordinal-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.
