Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025506, here are decompositions:

3 + 1025503 = 1025506
23 + 1025483 = 1025506
29 + 1025477 = 1025506
47 + 1025459 = 1025506
89 + 1025417 = 1025506
113 + 1025393 = 1025506
173 + 1025333 = 1025506
179 + 1025327 = 1025506

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 1,025,506 and was likely granted around 1912.

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