Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471780, here are decompositions:
- 11 + 471769 = 471780
- 31 + 471749 = 471780
- 59 + 471721 = 471780
- 61 + 471719 = 471780
- 83 + 471697 = 471780
- 97 + 471683 = 471780
- 103 + 471677 = 471780
- 107 + 471673 = 471780
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 471,780 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 471780 first appears in π at position 377,829 of the decimal expansion (the 377,829ordinal-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.
