Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135204, here are decompositions:
- 7 + 135197 = 135204
- 11 + 135193 = 135204
- 23 + 135181 = 135204
- 31 + 135173 = 135204
- 53 + 135151 = 135204
- 73 + 135131 = 135204
- 103 + 135101 = 135204
- 127 + 135077 = 135204
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 135,204 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 135204 first appears in π at position 729,431 of the decimal expansion (the 729,431ordinal-suffix:st 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.
