Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100830, here are decompositions:

7 + 100823 = 100830
19 + 100811 = 100830
29 + 100801 = 100830
31 + 100799 = 100830
43 + 100787 = 100830
61 + 100769 = 100830
83 + 100747 = 100830
89 + 100741 = 100830

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 100,830 and was likely granted around 1870.

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