Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471580, here are decompositions:
- 41 + 471539 = 471580
- 47 + 471533 = 471580
- 59 + 471521 = 471580
- 71 + 471509 = 471580
- 113 + 471467 = 471580
- 173 + 471407 = 471580
- 191 + 471389 = 471580
- 227 + 471353 = 471580
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 471,580 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 471580 first appears in π at position 790,937 of the decimal expansion (the 790,937ordinal-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.
