Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999404, here are decompositions:
- 73 + 999331 = 999404
- 97 + 999307 = 999404
- 223 + 999181 = 999404
- 271 + 999133 = 999404
- 313 + 999091 = 999404
- 337 + 999067 = 999404
- 397 + 999007 = 999404
- 421 + 998983 = 999404
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 999,404 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 999404 first appears in π at position 425,406 of the decimal expansion (the 425,406ordinal-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.
