Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135684, here are decompositions:
- 13 + 135671 = 135684
- 23 + 135661 = 135684
- 37 + 135647 = 135684
- 47 + 135637 = 135684
- 61 + 135623 = 135684
- 67 + 135617 = 135684
- 71 + 135613 = 135684
- 83 + 135601 = 135684
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 135,684 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 135684 first appears in π at position 70,254 of the decimal expansion (the 70,254ordinal-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.
