Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491246, here are decompositions:
- 79 + 491167 = 491246
- 97 + 491149 = 491246
- 109 + 491137 = 491246
- 163 + 491083 = 491246
- 277 + 490969 = 491246
- 397 + 490849 = 491246
- 409 + 490837 = 491246
- 463 + 490783 = 491246
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 491,246 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 491246 first appears in π at position 228,778 of the decimal expansion (the 228,778ordinal-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.
