Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028998, here are decompositions:

17 + 1028981 = 1028998
29 + 1028969 = 1028998
41 + 1028957 = 1028998
59 + 1028939 = 1028998
251 + 1028747 = 1028998
317 + 1028681 = 1028998
401 + 1028597 = 1028998
419 + 1028579 = 1028998

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 1,028,998 and was likely granted around 1912.

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