Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040644, here are decompositions:
- 47 + 1040597 = 1040644
- 113 + 1040531 = 1040644
- 197 + 1040447 = 1040644
- 233 + 1040411 = 1040644
- 257 + 1040387 = 1040644
- 263 + 1040381 = 1040644
- 317 + 1040327 = 1040644
- 461 + 1040183 = 1040644
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 1,040,644 and was likely granted around 1912.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
