Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940440, here are decompositions:
- 19 + 940421 = 940440
- 37 + 940403 = 940440
- 41 + 940399 = 940440
- 71 + 940369 = 940440
- 79 + 940361 = 940440
- 89 + 940351 = 940440
- 113 + 940327 = 940440
- 139 + 940301 = 940440
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 940,440 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
