Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000478, here are decompositions:
- 97 + 1000381 = 1000478
- 229 + 1000249 = 1000478
- 307 + 1000171 = 1000478
- 379 + 1000099 = 1000478
- 397 + 1000081 = 1000478
- 439 + 1000039 = 1000478
- 499 + 999979 = 1000478
- 547 + 999931 = 1000478
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 1,000,478 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
