Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103720, here are decompositions:

17 + 103703 = 103720
101 + 103619 = 103720
107 + 103613 = 103720
137 + 103583 = 103720
167 + 103553 = 103720
191 + 103529 = 103720
263 + 103457 = 103720
269 + 103451 = 103720

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 103.720 and was likely granted around 1870.

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