Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025800, here are decompositions:

11 + 1025789 = 1025800
53 + 1025747 = 1025800
59 + 1025741 = 1025800
107 + 1025693 = 1025800
131 + 1025669 = 1025800
179 + 1025621 = 1025800
239 + 1025561 = 1025800
257 + 1025543 = 1025800

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 1,025,800 and was likely granted around 1912.

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