Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103648, here are decompositions:

5 + 103643 = 103648
29 + 103619 = 103648
71 + 103577 = 103648
137 + 103511 = 103648
191 + 103457 = 103648
197 + 103451 = 103648
227 + 103421 = 103648
239 + 103409 = 103648

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 103,648 and was likely granted around 1870.

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