Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491416, here are decompositions:
- 59 + 491357 = 491416
- 83 + 491333 = 491416
- 89 + 491327 = 491416
- 137 + 491279 = 491416
- 197 + 491219 = 491416
- 257 + 491159 = 491416
- 449 + 490967 = 491416
- 467 + 490949 = 491416
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 491,416 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 491416 first appears in π at position 22,730 of the decimal expansion (the 22,730ordinal-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.
