Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102490, here are decompositions:

29 + 102461 = 102490
53 + 102437 = 102490
83 + 102407 = 102490
131 + 102359 = 102490
173 + 102317 = 102490
191 + 102299 = 102490
197 + 102293 = 102490
239 + 102251 = 102490

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 102,490 and was likely granted around 1870.

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