Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991346, here are decompositions:
- 3 + 991343 = 991346
- 19 + 991327 = 991346
- 73 + 991273 = 991346
- 199 + 991147 = 991346
- 277 + 991069 = 991346
- 283 + 991063 = 991346
- 337 + 991009 = 991346
- 373 + 990973 = 991346
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 991,346 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 991346 first appears in π at position 619,755 of the decimal expansion (the 619,755ordinal-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.
