Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102542, here are decompositions:

3 + 102539 = 102542
19 + 102523 = 102542
43 + 102499 = 102542
61 + 102481 = 102542
109 + 102433 = 102542
241 + 102301 = 102542
283 + 102259 = 102542
313 + 102229 = 102542

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 102,542 and was likely granted around 1870.

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