Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003390, here are decompositions:

23 + 1003367 = 1003390
29 + 1003361 = 1003390
41 + 1003349 = 1003390
53 + 1003337 = 1003390
83 + 1003307 = 1003390
131 + 1003259 = 1003390
149 + 1003241 = 1003390
191 + 1003199 = 1003390

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,003,390 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
