Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470664, here are decompositions:
- 11 + 470653 = 470664
- 13 + 470651 = 470664
- 17 + 470647 = 470664
- 37 + 470627 = 470664
- 43 + 470621 = 470664
- 67 + 470597 = 470664
- 71 + 470593 = 470664
- 113 + 470551 = 470664
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 470,664 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 470664 first appears in π at position 343,991 of the decimal expansion (the 343,991ordinal-suffix:st 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.
