Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001900, here are decompositions:

61 + 1001839 = 1001900
79 + 1001821 = 1001900
103 + 1001797 = 1001900
157 + 1001743 = 1001900
241 + 1001659 = 1001900
271 + 1001629 = 1001900
307 + 1001593 = 1001900
313 + 1001587 = 1001900

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 1,001,900 and was likely granted around 1911.

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