Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931100, here are decompositions:

3 + 931097 = 931100
13 + 931087 = 931100
97 + 931003 = 931100
109 + 930991 = 931100
127 + 930973 = 931100
211 + 930889 = 931100
241 + 930859 = 931100
283 + 930817 = 931100

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 931,100 and was likely granted around 1909.

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