Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990104, here are decompositions:
- 61 + 990043 = 990104
- 67 + 990037 = 990104
- 103 + 990001 = 990104
- 127 + 989977 = 990104
- 277 + 989827 = 990104
- 307 + 989797 = 990104
- 433 + 989671 = 990104
- 457 + 989647 = 990104
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 990,104 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 990104 first appears in π at position 279,091 of the decimal expansion (the 279,091ordinal-suffix:st 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.
