Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491260, here are decompositions:
- 41 + 491219 = 491260
- 47 + 491213 = 491260
- 59 + 491201 = 491260
- 89 + 491171 = 491260
- 101 + 491159 = 491260
- 131 + 491129 = 491260
- 179 + 491081 = 491260
- 257 + 491003 = 491260
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 491,260 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 491260 first appears in π at position 939,812 of the decimal expansion (the 939,812ordinal-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.
