Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187002, here are decompositions:

43 + 186959 = 187002
113 + 186889 = 187002
131 + 186871 = 187002
229 + 186773 = 187002
239 + 186763 = 187002
241 + 186761 = 187002
269 + 186733 = 187002
293 + 186709 = 187002

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 187,002 and was likely granted around 1875.

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