Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102120, here are decompositions:

13 + 102107 = 102120
17 + 102103 = 102120
19 + 102101 = 102120
41 + 102079 = 102120
43 + 102077 = 102120
59 + 102061 = 102120
61 + 102059 = 102120
89 + 102031 = 102120

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 102,120 and was likely granted around 1870.

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