Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136242, here are decompositions:
- 5 + 136237 = 136242
- 19 + 136223 = 136242
- 53 + 136189 = 136242
- 79 + 136163 = 136242
- 103 + 136139 = 136242
- 109 + 136133 = 136242
- 131 + 136111 = 136242
- 149 + 136093 = 136242
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 136,242 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 136242 first appears in π at position 618,856 of the decimal expansion (the 618,856ordinal-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.
