Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017890, here are decompositions:

31 + 1017859 = 1017890
43 + 1017847 = 1017890
73 + 1017817 = 1017890
103 + 1017787 = 1017890
109 + 1017781 = 1017890
241 + 1017649 = 1017890
277 + 1017613 = 1017890
283 + 1017607 = 1017890

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 1,017,890 and was likely granted around 1911.

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