Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047866, here are decompositions:

7 + 1047859 = 1047866
103 + 1047763 = 1047866
163 + 1047703 = 1047866
199 + 1047667 = 1047866
277 + 1047589 = 1047866
307 + 1047559 = 1047866
367 + 1047499 = 1047866
397 + 1047469 = 1047866

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 1,047,866 and was likely granted around 1912.

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