Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135664, here are decompositions:
- 3 + 135661 = 135664
- 17 + 135647 = 135664
- 41 + 135623 = 135664
- 47 + 135617 = 135664
- 71 + 135593 = 135664
- 83 + 135581 = 135664
- 131 + 135533 = 135664
- 167 + 135497 = 135664
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 135,664 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 135664 first appears in π at position 391,229 of the decimal expansion (the 391,229ordinal-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.
