Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102002, here are decompositions:

3 + 101999 = 102002
73 + 101929 = 102002
139 + 101863 = 102002
163 + 101839 = 102002
283 + 101719 = 102002
349 + 101653 = 102002
421 + 101581 = 102002
499 + 101503 = 102002

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 102,002 and was likely granted around 1870.

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