Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100660, here are decompositions:

11 + 100649 = 100660
47 + 100613 = 100660
101 + 100559 = 100660
113 + 100547 = 100660
137 + 100523 = 100660
149 + 100511 = 100660
167 + 100493 = 100660
191 + 100469 = 100660

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 100,660 and was likely granted around 1870.

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