Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478404, here are decompositions:
- 5 + 478399 = 478404
- 13 + 478391 = 478404
- 53 + 478351 = 478404
- 61 + 478343 = 478404
- 83 + 478321 = 478404
- 131 + 478273 = 478404
- 151 + 478253 = 478404
- 163 + 478241 = 478404
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 478,404 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 478404 first appears in π at position 594,951 of the decimal expansion (the 594,951ordinal-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.
