Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022400, here are decompositions:
- 11 + 1022389 = 1022400
- 13 + 1022387 = 1022400
- 17 + 1022383 = 1022400
- 19 + 1022381 = 1022400
- 23 + 1022377 = 1022400
- 59 + 1022341 = 1022400
- 97 + 1022303 = 1022400
- 109 + 1022291 = 1022400
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 1,022,400 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
