Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038428, here are decompositions:

7 + 1038421 = 1038428
19 + 1038409 = 1038428
37 + 1038391 = 1038428
109 + 1038319 = 1038428
229 + 1038199 = 1038428
241 + 1038187 = 1038428
271 + 1038157 = 1038428
409 + 1038019 = 1038428

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 1,038,428 and was likely granted around 1912.

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