Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020250, here are decompositions:

3 + 1020247 = 1020250
17 + 1020233 = 1020250
107 + 1020143 = 1020250
113 + 1020137 = 1020250
137 + 1020113 = 1020250
149 + 1020101 = 1020250
173 + 1020077 = 1020250
191 + 1020059 = 1020250

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 1,020,250 and was likely granted around 1911.

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