Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471720, here are decompositions:
- 17 + 471703 = 471720
- 23 + 471697 = 471720
- 37 + 471683 = 471720
- 43 + 471677 = 471720
- 47 + 471673 = 471720
- 61 + 471659 = 471720
- 71 + 471649 = 471720
- 79 + 471641 = 471720
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 471,720 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 471720 first appears in π at position 474,631 of the decimal expansion (the 474,631ordinal-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.
