Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491370, here are decompositions:
- 13 + 491357 = 491370
- 17 + 491353 = 491370
- 29 + 491341 = 491370
- 31 + 491339 = 491370
- 37 + 491333 = 491370
- 41 + 491329 = 491370
- 43 + 491327 = 491370
- 71 + 491299 = 491370
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 491,370 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 491370 first appears in π at position 144,622 of the decimal expansion (the 144,622ordinal-suffix:nd 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.
