Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121300, here are decompositions:

17 + 121283 = 121300
29 + 121271 = 121300
41 + 121259 = 121300
71 + 121229 = 121300
131 + 121169 = 121300
149 + 121151 = 121300
233 + 121067 = 121300
239 + 121061 = 121300

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 121,300 and was likely granted around 1871.

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