Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120306, here are decompositions:

7 + 120299 = 120306
13 + 120293 = 120306
23 + 120283 = 120306
29 + 120277 = 120306
59 + 120247 = 120306
73 + 120233 = 120306
83 + 120223 = 120306
97 + 120209 = 120306

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 120,306 and was likely granted around 1871.

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