Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050390, here are decompositions:

23 + 1050367 = 1050390
41 + 1050349 = 1050390
53 + 1050337 = 1050390
59 + 1050331 = 1050390
67 + 1050323 = 1050390
73 + 1050317 = 1050390
83 + 1050307 = 1050390
109 + 1050281 = 1050390

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 1,050,390 and was likely granted around 1912.

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