Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025578, here are decompositions:

17 + 1025561 = 1025578
41 + 1025537 = 1025578
101 + 1025477 = 1025578
227 + 1025351 = 1025578
251 + 1025327 = 1025578
311 + 1025267 = 1025578
317 + 1025261 = 1025578
347 + 1025231 = 1025578

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 1,025,578 and was likely granted around 1912.

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