Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030900, here are decompositions:

11 + 1030889 = 1030900
53 + 1030847 = 1030900
83 + 1030817 = 1030900
89 + 1030811 = 1030900
107 + 1030793 = 1030900
113 + 1030787 = 1030900
137 + 1030763 = 1030900
149 + 1030751 = 1030900

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 1,030,900 and was likely granted around 1912.

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