Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030380, here are decompositions:

11 + 1030369 = 1030380
19 + 1030361 = 1030380
23 + 1030357 = 1030380
31 + 1030349 = 1030380
73 + 1030307 = 1030380
83 + 1030297 = 1030380
89 + 1030291 = 1030380
139 + 1030241 = 1030380

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 1,030,380 and was likely granted around 1912.

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