Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025530, here are decompositions:

17 + 1025513 = 1025530
47 + 1025483 = 1025530
53 + 1025477 = 1025530
71 + 1025459 = 1025530
113 + 1025417 = 1025530
137 + 1025393 = 1025530
179 + 1025351 = 1025530
197 + 1025333 = 1025530

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 1,025,530 and was likely granted around 1912.

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