Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561300, here are decompositions:

23 + 561277 = 561300
71 + 561229 = 561300
101 + 561199 = 561300
109 + 561191 = 561300
127 + 561173 = 561300
139 + 561161 = 561300
191 + 561109 = 561300
197 + 561103 = 561300

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 561,300 and was likely granted around 1895.

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