Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031100, here are decompositions:

19 + 1031081 = 1031100
43 + 1031057 = 1031100
47 + 1031053 = 1031100
53 + 1031047 = 1031100
97 + 1031003 = 1031100
107 + 1030993 = 1031100
113 + 1030987 = 1031100
149 + 1030951 = 1031100

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 1,031,100 and was likely granted around 1912.

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