Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108630, here are decompositions:

43 + 108587 = 108630
59 + 108571 = 108630
73 + 108557 = 108630
89 + 108541 = 108630
97 + 108533 = 108630
101 + 108529 = 108630
113 + 108517 = 108630
127 + 108503 = 108630

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 108,630 and was likely granted around 1870.

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