Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000430, here are decompositions:

3 + 1000427 = 1000430
7 + 1000423 = 1000430
37 + 1000393 = 1000430
73 + 1000357 = 1000430
97 + 1000333 = 1000430
127 + 1000303 = 1000430
139 + 1000291 = 1000430
157 + 1000273 = 1000430

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 1,000,430 and was likely granted around 1911.

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