Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021118, here are decompositions:

31 + 1021087 = 1021118
37 + 1021081 = 1021118
127 + 1020991 = 1021118
139 + 1020979 = 1021118
151 + 1020967 = 1021118
157 + 1020961 = 1021118
211 + 1020907 = 1021118
271 + 1020847 = 1021118

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 1,021,118 and was likely granted around 1912.

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