Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101518, here are decompositions:

5 + 101513 = 101518
17 + 101501 = 101518
29 + 101489 = 101518
41 + 101477 = 101518
89 + 101429 = 101518
107 + 101411 = 101518
239 + 101279 = 101518
251 + 101267 = 101518

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 101,518 and was likely granted around 1870.

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