Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491746, here are decompositions:
- 107 + 491639 = 491746
- 113 + 491633 = 491746
- 257 + 491489 = 491746
- 263 + 491483 = 491746
- 317 + 491429 = 491746
- 389 + 491357 = 491746
- 419 + 491327 = 491746
- 449 + 491297 = 491746
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 491,746 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 491746 first appears in π at position 246,493 of the decimal expansion (the 246,493ordinal-suffix:rd 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.
