Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022258, here are decompositions:

7 + 1022251 = 1022258
67 + 1022191 = 1022258
79 + 1022179 = 1022258
199 + 1022059 = 1022258
241 + 1022017 = 1022258
379 + 1021879 = 1022258
397 + 1021861 = 1022258
409 + 1021849 = 1022258

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 1,022,258 and was likely granted around 1912.

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