Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025146, here are decompositions:

47 + 1025099 = 1025146
53 + 1025093 = 1025146
107 + 1025039 = 1025146
137 + 1025009 = 1025146
149 + 1024997 = 1025146
263 + 1024883 = 1025146
293 + 1024853 = 1025146
347 + 1024799 = 1025146

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 1,025,146 and was likely granted around 1912.

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