Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990050, here are decompositions:

7 + 990043 = 990050
13 + 990037 = 990050
37 + 990013 = 990050
73 + 989977 = 990050
79 + 989971 = 990050
163 + 989887 = 990050
181 + 989869 = 990050
211 + 989839 = 990050

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 990,050 and was likely granted around 1911.

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