Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136458, here are decompositions:
- 5 + 136453 = 136458
- 11 + 136447 = 136458
- 29 + 136429 = 136458
- 37 + 136421 = 136458
- 41 + 136417 = 136458
- 59 + 136399 = 136458
- 61 + 136397 = 136458
- 79 + 136379 = 136458
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 136,458 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 136458 first appears in π at position 521,932 of the decimal expansion (the 521,932ordinal-suffix:nd 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.
