Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136404, here are decompositions:
- 5 + 136399 = 136404
- 7 + 136397 = 136404
- 11 + 136393 = 136404
- 31 + 136373 = 136404
- 43 + 136361 = 136404
- 53 + 136351 = 136404
- 61 + 136343 = 136404
- 67 + 136337 = 136404
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 136,404 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 136404 first appears in π at position 333,669 of the decimal expansion (the 333,669ordinal-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.
