Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102526, here are decompositions:

3 + 102523 = 102526
23 + 102503 = 102526
29 + 102497 = 102526
89 + 102437 = 102526
167 + 102359 = 102526
197 + 102329 = 102526
227 + 102299 = 102526
233 + 102293 = 102526

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 102,526 and was likely granted around 1870.

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