Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123406, here are decompositions:
- 5 + 123401 = 123406
- 29 + 123377 = 123406
- 83 + 123323 = 123406
- 137 + 123269 = 123406
- 167 + 123239 = 123406
- 197 + 123209 = 123406
- 263 + 123143 = 123406
- 293 + 123113 = 123406
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 123,406 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 123406 first appears in π at position 971,097 of the decimal expansion (the 971,097ordinal-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.
