Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042390, here are decompositions:

17 + 1042373 = 1042390
59 + 1042331 = 1042390
131 + 1042259 = 1042390
149 + 1042241 = 1042390
179 + 1042211 = 1042390
197 + 1042193 = 1042390
257 + 1042133 = 1042390
269 + 1042121 = 1042390

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 1,042,390 and was likely granted around 1912.

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