Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136240, here are decompositions:
- 3 + 136237 = 136240
- 17 + 136223 = 136240
- 23 + 136217 = 136240
- 47 + 136193 = 136240
- 101 + 136139 = 136240
- 107 + 136133 = 136240
- 173 + 136067 = 136240
- 197 + 136043 = 136240
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 136,240 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 136240 first appears in π at position 339,828 of the decimal expansion (the 339,828ordinal-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.
