Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000042, here are decompositions:

3 + 1000039 = 1000042
5 + 1000037 = 1000042
59 + 999983 = 1000042
83 + 999959 = 1000042
89 + 999953 = 1000042
179 + 999863 = 1000042
233 + 999809 = 1000042
269 + 999773 = 1000042

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 1,000,042 and was likely granted around 1911.

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