Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491064, here are decompositions:
- 5 + 491059 = 491064
- 23 + 491041 = 491064
- 61 + 491003 = 491064
- 71 + 490993 = 491064
- 73 + 490991 = 491064
- 97 + 490967 = 491064
- 107 + 490957 = 491064
- 113 + 490951 = 491064
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 491,064 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 491064 first appears in π at position 90,759 of the decimal expansion (the 90,759ordinal-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.
