Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122466, here are decompositions:
- 13 + 122453 = 122466
- 17 + 122449 = 122466
- 23 + 122443 = 122466
- 67 + 122399 = 122466
- 73 + 122393 = 122466
- 79 + 122387 = 122466
- 103 + 122363 = 122466
- 139 + 122327 = 122466
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 122,466 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 122466 first appears in π at position 460,768 of the decimal expansion (the 460,768ordinal-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.
