Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491122, here are decompositions:
- 41 + 491081 = 491122
- 83 + 491039 = 491122
- 131 + 490991 = 491122
- 173 + 490949 = 491122
- 263 + 490859 = 491122
- 293 + 490829 = 491122
- 353 + 490769 = 491122
- 389 + 490733 = 491122
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 491,122 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 491122 first appears in π at position 426,376 of the decimal expansion (the 426,376ordinal-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.
