Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135804, here are decompositions:
- 5 + 135799 = 135804
- 17 + 135787 = 135804
- 23 + 135781 = 135804
- 47 + 135757 = 135804
- 61 + 135743 = 135804
- 73 + 135731 = 135804
- 83 + 135721 = 135804
- 103 + 135701 = 135804
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 135,804 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 135804 first appears in π at position 611,868 of the decimal expansion (the 611,868ordinal-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.
