Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471772, here are decompositions:
- 3 + 471769 = 471772
- 23 + 471749 = 471772
- 53 + 471719 = 471772
- 89 + 471683 = 471772
- 101 + 471671 = 471772
- 113 + 471659 = 471772
- 131 + 471641 = 471772
- 179 + 471593 = 471772
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 471,772 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 471772 first appears in π at position 631,237 of the decimal expansion (the 631,237ordinal-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.
