Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491346, here are decompositions:
- 5 + 491341 = 491346
- 7 + 491339 = 491346
- 13 + 491333 = 491346
- 17 + 491329 = 491346
- 19 + 491327 = 491346
- 47 + 491299 = 491346
- 67 + 491279 = 491346
- 73 + 491273 = 491346
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 491,346 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 491346 first appears in π at position 853,192 of the decimal expansion (the 853,192ordinal-suffix:nd 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.
