Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103644, here are decompositions:

31 + 103613 = 103644
53 + 103591 = 103644
61 + 103583 = 103644
67 + 103577 = 103644
71 + 103573 = 103644
83 + 103561 = 103644
173 + 103471 = 103644
193 + 103451 = 103644

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 103.644 and was likely granted around 1870.

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