Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031806, here are decompositions:

47 + 1031759 = 1031806
53 + 1031753 = 1031806
89 + 1031717 = 1031806
137 + 1031669 = 1031806
173 + 1031633 = 1031806
197 + 1031609 = 1031806
257 + 1031549 = 1031806
317 + 1031489 = 1031806

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 1,031,806 and was likely granted around 1912.

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