Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122464, here are decompositions:
- 11 + 122453 = 122464
- 71 + 122393 = 122464
- 101 + 122363 = 122464
- 137 + 122327 = 122464
- 191 + 122273 = 122464
- 197 + 122267 = 122464
- 233 + 122231 = 122464
- 257 + 122207 = 122464
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 122,464 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 122464 first appears in π at position 12,819 of the decimal expansion (the 12,819ordinal-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.
