Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023838, here are decompositions:

5 + 1023833 = 1023838
17 + 1023821 = 1023838
107 + 1023731 = 1023838
281 + 1023557 = 1023838
317 + 1023521 = 1023838
419 + 1023419 = 1023838
449 + 1023389 = 1023838
509 + 1023329 = 1023838

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 1,023,838 and was likely granted around 1912.

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