Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025278, here are decompositions:

5 + 1025273 = 1025278
11 + 1025267 = 1025278
17 + 1025261 = 1025278
47 + 1025231 = 1025278
131 + 1025147 = 1025278
167 + 1025111 = 1025278
179 + 1025099 = 1025278
197 + 1025081 = 1025278

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 1,025,278 and was likely granted around 1912.

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