Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981104, here are decompositions:
- 13 + 981091 = 981104
- 31 + 981073 = 981104
- 37 + 981067 = 981104
- 43 + 981061 = 981104
- 67 + 981037 = 981104
- 193 + 980911 = 981104
- 211 + 980893 = 981104
- 277 + 980827 = 981104
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 981,104 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 981104 first appears in π at position 462,048 of the decimal expansion (the 462,048ordinal-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.
