Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100722, here are decompositions:

19 + 100703 = 100722
23 + 100699 = 100722
29 + 100693 = 100722
53 + 100669 = 100722
73 + 100649 = 100722
101 + 100621 = 100722
109 + 100613 = 100722
113 + 100609 = 100722

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 100,722 and was likely granted around 1870.

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