Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561900, here are decompositions:

61 + 561839 = 561900
71 + 561829 = 561900
103 + 561797 = 561900
113 + 561787 = 561900
139 + 561761 = 561900
167 + 561733 = 561900
197 + 561703 = 561900
233 + 561667 = 561900

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 561,900 and was likely granted around 1895.

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