Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002440, here are decompositions:
- 7 + 1002433 = 1002440
- 13 + 1002427 = 1002440
- 37 + 1002403 = 1002440
- 79 + 1002361 = 1002440
- 97 + 1002343 = 1002440
- 151 + 1002289 = 1002440
- 181 + 1002259 = 1002440
- 193 + 1002247 = 1002440
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 1,002,440 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
