Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047850, here are decompositions:

17 + 1047833 = 1047850
29 + 1047821 = 1047850
71 + 1047779 = 1047850
113 + 1047737 = 1047850
137 + 1047713 = 1047850
149 + 1047701 = 1047850
179 + 1047671 = 1047850
197 + 1047653 = 1047850

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 1,047,850 and was likely granted around 1912.

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