Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101256, here are decompositions:

47 + 101209 = 101256
53 + 101203 = 101256
59 + 101197 = 101256
73 + 101183 = 101256
83 + 101173 = 101256
97 + 101159 = 101256
107 + 101149 = 101256
137 + 101119 = 101256

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 101,256 and was likely granted around 1870.

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