Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491004, here are decompositions:
- 11 + 490993 = 491004
- 13 + 490991 = 491004
- 37 + 490967 = 491004
- 47 + 490957 = 491004
- 53 + 490951 = 491004
- 67 + 490937 = 491004
- 83 + 490921 = 491004
- 113 + 490891 = 491004
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 491,004 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 491004 first appears in π at position 37,760 of the decimal expansion (the 37,760ordinal-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.
