Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051850, here are decompositions:

3 + 1051847 = 1051850
31 + 1051819 = 1051850
61 + 1051789 = 1051850
103 + 1051747 = 1051850
211 + 1051639 = 1051850
229 + 1051621 = 1051850
307 + 1051543 = 1051850
379 + 1051471 = 1051850

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 1,051,850 and was likely granted around 1912.

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