Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100906, here are decompositions:

53 + 100853 = 100906
59 + 100847 = 100906
83 + 100823 = 100906
107 + 100799 = 100906
137 + 100769 = 100906
173 + 100733 = 100906
233 + 100673 = 100906
257 + 100649 = 100906

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 100,906 and was likely granted around 1870.

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