Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002238, here are decompositions:

11 + 1002227 = 1002238
47 + 1002191 = 1002238
89 + 1002149 = 1002238
137 + 1002101 = 1002238
257 + 1001981 = 1002238
431 + 1001807 = 1002238
569 + 1001669 = 1002238
599 + 1001639 = 1002238

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 1,002,238 and was likely granted around 1911.

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