Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481404, here are decompositions:
- 17 + 481387 = 481404
- 31 + 481373 = 481404
- 41 + 481363 = 481404
- 61 + 481343 = 481404
- 97 + 481307 = 481404
- 101 + 481303 = 481404
- 103 + 481301 = 481404
- 107 + 481297 = 481404
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 481,404 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 481404 first appears in π at position 899,239 of the decimal expansion (the 899,239ordinal-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.
