Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039438, here are decompositions:

11 + 1039427 = 1039438
17 + 1039421 = 1039438
89 + 1039349 = 1039438
131 + 1039307 = 1039438
149 + 1039289 = 1039438
251 + 1039187 = 1039438
269 + 1039169 = 1039438
311 + 1039127 = 1039438

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 1,039,438 and was likely granted around 1912.

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