Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8605404, here are decompositions:
- 43 + 8605361 = 8605404
- 97 + 8605307 = 8605404
- 107 + 8605297 = 8605404
- 131 + 8605273 = 8605404
- 163 + 8605241 = 8605404
- 167 + 8605237 = 8605404
- 173 + 8605231 = 8605404
- 193 + 8605211 = 8605404
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 8,605,404 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8605404 first appears in π at position 63,064 of the decimal expansion (the 63,064ordinal-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.
