Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581104, here are decompositions:
- 3 + 581101 = 581104
- 5 + 581099 = 581104
- 107 + 580997 = 581104
- 191 + 580913 = 581104
- 233 + 580871 = 581104
- 311 + 580793 = 581104
- 317 + 580787 = 581104
- 347 + 580757 = 581104
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 581,104 and was likely granted around 1896.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 581104 first appears in π at position 363,325 of the decimal expansion (the 363,325ordinal-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.
