Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109600, here are decompositions:

3 + 109597 = 109600
11 + 109589 = 109600
17 + 109583 = 109600
53 + 109547 = 109600
59 + 109541 = 109600
83 + 109517 = 109600
131 + 109469 = 109600
149 + 109451 = 109600

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 109,600 and was likely granted around 1871.

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