Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491466, here are decompositions:
- 5 + 491461 = 491466
- 37 + 491429 = 491466
- 43 + 491423 = 491466
- 89 + 491377 = 491466
- 109 + 491357 = 491466
- 113 + 491353 = 491466
- 127 + 491339 = 491466
- 137 + 491329 = 491466
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 491,466 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 491466 first appears in π at position 952,780 of the decimal expansion (the 952,780ordinal-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.
