Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581120, here are decompositions:

19 + 581101 = 581120
31 + 581089 = 581120
73 + 581047 = 581120
79 + 581041 = 581120
139 + 580981 = 581120
151 + 580969 = 581120
181 + 580939 = 581120
193 + 580927 = 581120

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 581,120 and was likely granted around 1896.

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