Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477520, here are decompositions:
- 3 + 477517 = 477520
- 23 + 477497 = 477520
- 59 + 477461 = 477520
- 137 + 477383 = 477520
- 179 + 477341 = 477520
- 191 + 477329 = 477520
- 227 + 477293 = 477520
- 311 + 477209 = 477520
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 477,520 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 477520 first appears in π at position 240,584 of the decimal expansion (the 240,584ordinal-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.
