Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123436, here are decompositions:
- 3 + 123433 = 123436
- 17 + 123419 = 123436
- 29 + 123407 = 123436
- 59 + 123377 = 123436
- 113 + 123323 = 123436
- 167 + 123269 = 123436
- 197 + 123239 = 123436
- 227 + 123209 = 123436
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 123,436 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 123436 first appears in π at position 377,060 of the decimal expansion (the 377,060ordinal-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.
