Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491184, here are decompositions:
- 13 + 491171 = 491184
- 17 + 491167 = 491184
- 47 + 491137 = 491184
- 101 + 491083 = 491184
- 103 + 491081 = 491184
- 181 + 491003 = 491184
- 191 + 490993 = 491184
- 193 + 490991 = 491184
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 491,184 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 491184 first appears in π at position 394,517 of the decimal expansion (the 394,517ordinal-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.
