Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049818, here are decompositions:

71 + 1049747 = 1049818
101 + 1049717 = 1049818
131 + 1049687 = 1049818
137 + 1049681 = 1049818
179 + 1049639 = 1049818
269 + 1049549 = 1049818
281 + 1049537 = 1049818
347 + 1049471 = 1049818

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 1,049,818 and was likely granted around 1912.

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