Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136664, here are decompositions:
- 7 + 136657 = 136664
- 13 + 136651 = 136664
- 43 + 136621 = 136664
- 61 + 136603 = 136664
- 127 + 136537 = 136664
- 163 + 136501 = 136664
- 181 + 136483 = 136664
- 193 + 136471 = 136664
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 136,664 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 136664 first appears in π at position 700,336 of the decimal expansion (the 700,336ordinal-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.
