Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471390, here are decompositions:
- 37 + 471353 = 471390
- 89 + 471301 = 471390
- 107 + 471283 = 471390
- 109 + 471281 = 471390
- 113 + 471277 = 471390
- 131 + 471259 = 471390
- 137 + 471253 = 471390
- 149 + 471241 = 471390
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 471,390 and was likely granted around 1891.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
