Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101258, here are decompositions:

37 + 101221 = 101258
61 + 101197 = 101258
97 + 101161 = 101258
109 + 101149 = 101258
139 + 101119 = 101258
151 + 101107 = 101258
271 + 100987 = 101258
277 + 100981 = 101258

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 101,258 and was likely granted around 1870.

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