Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009430, here are decompositions:

13 + 1009417 = 1009430
31 + 1009399 = 1009430
43 + 1009387 = 1009430
61 + 1009369 = 1009430
73 + 1009357 = 1009430
109 + 1009321 = 1009430
127 + 1009303 = 1009430
139 + 1009291 = 1009430

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 1,009,430 and was likely granted around 1911.

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