Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101270, here are decompositions:

3 + 101267 = 101270
61 + 101209 = 101270
67 + 101203 = 101270
73 + 101197 = 101270
97 + 101173 = 101270
109 + 101161 = 101270
151 + 101119 = 101270
157 + 101113 = 101270

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 101,270 and was likely granted around 1870.

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