Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136864, here are decompositions:
- 3 + 136861 = 136864
- 5 + 136859 = 136864
- 23 + 136841 = 136864
- 53 + 136811 = 136864
- 113 + 136751 = 136864
- 131 + 136733 = 136864
- 137 + 136727 = 136864
- 173 + 136691 = 136864
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 136,864 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 136864 first appears in π at position 768,780 of the decimal expansion (the 768,780ordinal-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.
