Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491378, here are decompositions:
- 7 + 491371 = 491378
- 37 + 491341 = 491378
- 79 + 491299 = 491378
- 127 + 491251 = 491378
- 211 + 491167 = 491378
- 229 + 491149 = 491378
- 241 + 491137 = 491378
- 337 + 491041 = 491378
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 491,378 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 491378 first appears in π at position 595,627 of the decimal expansion (the 595,627ordinal-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.
