Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005450, here are decompositions:
- 11 + 1005439 = 1005450
- 13 + 1005437 = 1005450
- 23 + 1005427 = 1005450
- 37 + 1005413 = 1005450
- 41 + 1005409 = 1005450
- 59 + 1005391 = 1005450
- 79 + 1005371 = 1005450
- 101 + 1005349 = 1005450
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 1,005,450 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
