Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491248, here are decompositions:
- 29 + 491219 = 491248
- 47 + 491201 = 491248
- 89 + 491159 = 491248
- 167 + 491081 = 491248
- 257 + 490991 = 491248
- 281 + 490967 = 491248
- 311 + 490937 = 491248
- 389 + 490859 = 491248
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 491,248 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 491248 first appears in π at position 683,030 of the decimal expansion (the 683,030ordinal-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.
