Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104490, here are decompositions:
- 11 + 104479 = 104490
- 17 + 104473 = 104490
- 19 + 104471 = 104490
- 31 + 104459 = 104490
- 73 + 104417 = 104490
- 97 + 104393 = 104490
- 107 + 104383 = 104490
- 109 + 104381 = 104490
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 104,490 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 104490 first appears in π at position 194,621 of the decimal expansion (the 194,621ordinal-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.
