Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491304, here are decompositions:
- 5 + 491299 = 491304
- 7 + 491297 = 491304
- 31 + 491273 = 491304
- 43 + 491261 = 491304
- 53 + 491251 = 491304
- 103 + 491201 = 491304
- 137 + 491167 = 491304
- 167 + 491137 = 491304
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 491,304 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 491304 first appears in π at position 135,457 of the decimal expansion (the 135,457ordinal-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.
