Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104980, here are decompositions:

47 + 104933 = 104980
89 + 104891 = 104980
101 + 104879 = 104980
131 + 104849 = 104980
149 + 104831 = 104980
179 + 104801 = 104980
191 + 104789 = 104980
251 + 104729 = 104980

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 104 980 and was likely granted around 1870.

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