Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122446, here are decompositions:
- 3 + 122443 = 122446
- 47 + 122399 = 122446
- 53 + 122393 = 122446
- 59 + 122387 = 122446
- 83 + 122363 = 122446
- 167 + 122279 = 122446
- 173 + 122273 = 122446
- 179 + 122267 = 122446
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 122,446 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 122446 first appears in π at position 174,295 of the decimal expansion (the 174,295ordinal-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.
