Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101500, here are decompositions:

11 + 101489 = 101500
17 + 101483 = 101500
23 + 101477 = 101500
71 + 101429 = 101500
89 + 101411 = 101500
101 + 101399 = 101500
137 + 101363 = 101500
167 + 101333 = 101500

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 101,500 and was likely granted around 1870.

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