Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123526, here are decompositions:
- 23 + 123503 = 123526
- 47 + 123479 = 123526
- 107 + 123419 = 123526
- 149 + 123377 = 123526
- 257 + 123269 = 123526
- 317 + 123209 = 123526
- 383 + 123143 = 123526
- 443 + 123083 = 123526
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 123,526 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 123526 first appears in π at position 686,034 of the decimal expansion (the 686,034ordinal-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.
