Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040900, here are decompositions:

19 + 1040881 = 1040900
43 + 1040857 = 1040900
67 + 1040833 = 1040900
73 + 1040827 = 1040900
79 + 1040821 = 1040900
97 + 1040803 = 1040900
103 + 1040797 = 1040900
151 + 1040749 = 1040900

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 1,040,900 and was likely granted around 1912.

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