Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021278, here are decompositions:

7 + 1021271 = 1021278
17 + 1021261 = 1021278
19 + 1021259 = 1021278
61 + 1021217 = 1021278
79 + 1021199 = 1021278
149 + 1021129 = 1021278
151 + 1021127 = 1021278
191 + 1021087 = 1021278

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 1,021,278 and was likely granted around 1912.

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