Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025220, here are decompositions:

11 + 1025209 = 1025220
17 + 1025203 = 1025220
23 + 1025197 = 1025220
59 + 1025161 = 1025220
67 + 1025153 = 1025220
71 + 1025149 = 1025220
73 + 1025147 = 1025220
83 + 1025137 = 1025220

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 1,025,220 and was likely granted around 1912.

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