Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024900, here are decompositions:

17 + 1024883 = 1024900
29 + 1024871 = 1024900
47 + 1024853 = 1024900
101 + 1024799 = 1024900
179 + 1024721 = 1024900
197 + 1024703 = 1024900
311 + 1024589 = 1024900
353 + 1024547 = 1024900

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 1,024,900 and was likely granted around 1912.

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