Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023278, here are decompositions:

19 + 1023259 = 1023278
79 + 1023199 = 1023278
199 + 1023079 = 1023278
211 + 1023067 = 1023278
241 + 1023037 = 1023278
349 + 1022929 = 1023278
367 + 1022911 = 1023278
379 + 1022899 = 1023278

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 1,023,278 and was likely granted around 1912.

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