Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025400, here are decompositions:

7 + 1025393 = 1025400
17 + 1025383 = 1025400
53 + 1025347 = 1025400
67 + 1025333 = 1025400
73 + 1025327 = 1025400
97 + 1025303 = 1025400
127 + 1025273 = 1025400
139 + 1025261 = 1025400

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 1,025,400 and was likely granted around 1912.

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