Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478476, here are decompositions:
- 17 + 478459 = 478476
- 23 + 478453 = 478476
- 43 + 478433 = 478476
- 59 + 478417 = 478476
- 73 + 478403 = 478476
- 137 + 478339 = 478476
- 223 + 478253 = 478476
- 233 + 478243 = 478476
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 478,476 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 478476 first appears in π at position 678,805 of the decimal expansion (the 678,805ordinal-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.
