Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471840, here are decompositions:
- 23 + 471817 = 471840
- 37 + 471803 = 471840
- 59 + 471781 = 471840
- 71 + 471769 = 471840
- 137 + 471703 = 471840
- 157 + 471683 = 471840
- 163 + 471677 = 471840
- 167 + 471673 = 471840
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 471,840 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
