Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016220, here are decompositions:

17 + 1016203 = 1016220
19 + 1016201 = 1016220
47 + 1016173 = 1016220
61 + 1016159 = 1016220
67 + 1016153 = 1016220
83 + 1016137 = 1016220
97 + 1016123 = 1016220
109 + 1016111 = 1016220

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 1,016,220 and was likely granted around 1911.

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