Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122406, here are decompositions:
- 5 + 122401 = 122406
- 7 + 122399 = 122406
- 13 + 122393 = 122406
- 17 + 122389 = 122406
- 19 + 122387 = 122406
- 43 + 122363 = 122406
- 59 + 122347 = 122406
- 79 + 122327 = 122406
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 122,406 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 122406 first appears in π at position 368,547 of the decimal expansion (the 368,547ordinal-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.
