Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042688, here are decompositions:

7 + 1042681 = 1042688
79 + 1042609 = 1042688
307 + 1042381 = 1042688
331 + 1042357 = 1042688
379 + 1042309 = 1042688
421 + 1042267 = 1042688
547 + 1042141 = 1042688
601 + 1042087 = 1042688

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 1,042,688 and was likely granted around 1912.

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