Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040018, here are decompositions:

19 + 1039999 = 1040018
97 + 1039921 = 1040018
127 + 1039891 = 1040018
181 + 1039837 = 1040018
229 + 1039789 = 1040018
337 + 1039681 = 1040018
367 + 1039651 = 1040018
541 + 1039477 = 1040018

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 1,040,018 and was likely granted around 1912.

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