Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105904, here are decompositions:
- 5 + 105899 = 105904
- 41 + 105863 = 105904
- 137 + 105767 = 105904
- 251 + 105653 = 105904
- 347 + 105557 = 105904
- 401 + 105503 = 105904
- 467 + 105437 = 105904
- 503 + 105401 = 105904
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 105,904 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 105904 first appears in π at position 47,291 of the decimal expansion (the 47,291ordinal-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.
