Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104912, here are decompositions:
- 43 + 104869 = 104912
- 61 + 104851 = 104912
- 109 + 104803 = 104912
- 139 + 104773 = 104912
- 151 + 104761 = 104912
- 211 + 104701 = 104912
- 229 + 104683 = 104912
- 421 + 104491 = 104912
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 104,912 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 104912 first appears in π at position 228,776 of the decimal expansion (the 228,776ordinal-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.
