Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021228, here are decompositions:

11 + 1021217 = 1021228
29 + 1021199 = 1021228
71 + 1021157 = 1021228
101 + 1021127 = 1021228
137 + 1021091 = 1021228
227 + 1021001 = 1021228
239 + 1020989 = 1021228
251 + 1020977 = 1021228

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 1,021,228 and was likely granted around 1912.

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