Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020230, here are decompositions:

7 + 1020223 = 1020230
67 + 1020163 = 1020230
73 + 1020157 = 1020230
151 + 1020079 = 1020230
181 + 1020049 = 1020230
193 + 1020037 = 1020230
223 + 1020007 = 1020230
229 + 1020001 = 1020230

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 1,020,230 and was likely granted around 1911.

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