Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000238, here are decompositions:

7 + 1000231 = 1000238
67 + 1000171 = 1000238
79 + 1000159 = 1000238
139 + 1000099 = 1000238
157 + 1000081 = 1000238
199 + 1000039 = 1000238
277 + 999961 = 1000238
307 + 999931 = 1000238

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 1,000,238 and was likely granted around 1911.

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