Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111600, here are decompositions:

7 + 111593 = 111600
19 + 111581 = 111600
23 + 111577 = 111600
61 + 111539 = 111600
67 + 111533 = 111600
79 + 111521 = 111600
103 + 111497 = 111600
107 + 111493 = 111600

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 111,600 and was likely granted around 1871.

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