Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020394, here are decompositions:

5 + 1020389 = 1020394
41 + 1020353 = 1020394
101 + 1020293 = 1020394
251 + 1020143 = 1020394
257 + 1020137 = 1020394
281 + 1020113 = 1020394
293 + 1020101 = 1020394
317 + 1020077 = 1020394

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 1,020,394 and was likely granted around 1911.

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