Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020900, here are decompositions:

7 + 1020893 = 1020900
19 + 1020881 = 1020900
47 + 1020853 = 1020900
53 + 1020847 = 1020900
59 + 1020841 = 1020900
61 + 1020839 = 1020900
73 + 1020827 = 1020900
79 + 1020821 = 1020900

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 1,020,900 and was likely granted around 1912.

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