Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005480, here are decompositions:
- 13 + 1005467 = 1005480
- 23 + 1005457 = 1005480
- 41 + 1005439 = 1005480
- 43 + 1005437 = 1005480
- 53 + 1005427 = 1005480
- 67 + 1005413 = 1005480
- 71 + 1005409 = 1005480
- 89 + 1005391 = 1005480
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 1,005,480 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
