Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042642, here are decompositions:

11 + 1042631 = 1042642
23 + 1042619 = 1042642
59 + 1042583 = 1042642
71 + 1042571 = 1042642
113 + 1042529 = 1042642
173 + 1042469 = 1042642
191 + 1042451 = 1042642
269 + 1042373 = 1042642

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 1,042,642 and was likely granted around 1912.

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