Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040240, here are decompositions:

13 + 1040227 = 1040240
37 + 1040203 = 1040240
73 + 1040167 = 1040240
79 + 1040161 = 1040240
127 + 1040113 = 1040240
139 + 1040101 = 1040240
151 + 1040089 = 1040240
181 + 1040059 = 1040240

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 1,040,240 and was likely granted around 1912.

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