Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 476840, here are decompositions:
- 37 + 476803 = 476840
- 97 + 476743 = 476840
- 103 + 476737 = 476840
- 127 + 476713 = 476840
- 139 + 476701 = 476840
- 157 + 476683 = 476840
- 181 + 476659 = 476840
- 193 + 476647 = 476840
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 476,840 and was likely granted around 1892.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
