Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491964, here are decompositions:
- 13 + 491951 = 491964
- 41 + 491923 = 491964
- 97 + 491867 = 491964
- 107 + 491857 = 491964
- 113 + 491851 = 491964
- 127 + 491837 = 491964
- 131 + 491833 = 491964
- 167 + 491797 = 491964
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 491,964 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 491964 first appears in π at position 474,486 of the decimal expansion (the 474,486ordinal-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.
