Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103728, here are decompositions:

5 + 103723 = 103728
29 + 103699 = 103728
41 + 103687 = 103728
47 + 103681 = 103728
59 + 103669 = 103728
71 + 103657 = 103728
109 + 103619 = 103728
137 + 103591 = 103728

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 103.728 and was likely granted around 1870.

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