Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477904, here are decompositions:
- 5 + 477899 = 477904
- 23 + 477881 = 477904
- 41 + 477863 = 477904
- 47 + 477857 = 477904
- 83 + 477821 = 477904
- 107 + 477797 = 477904
- 113 + 477791 = 477904
- 137 + 477767 = 477904
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 477,904 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 477904 first appears in π at position 76,787 of the decimal expansion (the 76,787ordinal-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.
