Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040400, here are decompositions:
- 13 + 1040387 = 1040400
- 19 + 1040381 = 1040400
- 29 + 1040371 = 1040400
- 47 + 1040353 = 1040400
- 61 + 1040339 = 1040400
- 73 + 1040327 = 1040400
- 89 + 1040311 = 1040400
- 173 + 1040227 = 1040400
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 1,040,400 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
