Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136724, here are decompositions:
- 13 + 136711 = 136724
- 31 + 136693 = 136724
- 67 + 136657 = 136724
- 73 + 136651 = 136724
- 103 + 136621 = 136724
- 151 + 136573 = 136724
- 193 + 136531 = 136724
- 223 + 136501 = 136724
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 136,724 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 136724 first appears in π at position 531,155 of the decimal expansion (the 531,155ordinal-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.
