Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470478, here are decompositions:
- 5 + 470473 = 470478
- 7 + 470471 = 470478
- 17 + 470461 = 470478
- 31 + 470447 = 470478
- 61 + 470417 = 470478
- 67 + 470411 = 470478
- 79 + 470399 = 470478
- 89 + 470389 = 470478
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 470,478 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 470478 first appears in π at position 651,884 of the decimal expansion (the 651,884ordinal-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.
