Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491710, here are decompositions:
- 3 + 491707 = 491710
- 41 + 491669 = 491710
- 59 + 491651 = 491710
- 71 + 491639 = 491710
- 83 + 491627 = 491710
- 173 + 491537 = 491710
- 179 + 491531 = 491710
- 227 + 491483 = 491710
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 491,710 and was likely granted around 1893.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 491710 first appears in π at position 153,640 of the decimal expansion (the 153,640ordinal-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.
