Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478424, here are decompositions:
- 3 + 478421 = 478424
- 7 + 478417 = 478424
- 13 + 478411 = 478424
- 73 + 478351 = 478424
- 103 + 478321 = 478424
- 151 + 478273 = 478424
- 181 + 478243 = 478424
- 211 + 478213 = 478424
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 478,424 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 478424 first appears in π at position 483,426 of the decimal expansion (the 483,426ordinal-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.
