Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136788, here are decompositions:
- 11 + 136777 = 136788
- 19 + 136769 = 136788
- 37 + 136751 = 136788
- 61 + 136727 = 136788
- 79 + 136709 = 136788
- 97 + 136691 = 136788
- 131 + 136657 = 136788
- 137 + 136651 = 136788
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 136,788 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 136788 first appears in π at position 243,727 of the decimal expansion (the 243,727ordinal-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.
