Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162002, here are decompositions:

3 + 161999 = 162002
19 + 161983 = 162002
31 + 161971 = 162002
79 + 161923 = 162002
163 + 161839 = 162002
223 + 161779 = 162002
229 + 161773 = 162002
241 + 161761 = 162002

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 162,002 and was likely granted around 1874.

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