Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006400, here are decompositions:
- 7 + 1006393 = 1006400
- 61 + 1006339 = 1006400
- 67 + 1006333 = 1006400
- 97 + 1006303 = 1006400
- 151 + 1006249 = 1006400
- 163 + 1006237 = 1006400
- 181 + 1006219 = 1006400
- 211 + 1006189 = 1006400
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 1,006,400 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
