Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190040, here are decompositions:

13 + 190027 = 190040
43 + 189997 = 190040
73 + 189967 = 190040
79 + 189961 = 190040
127 + 189913 = 190040
139 + 189901 = 190040
163 + 189877 = 190040
181 + 189859 = 190040

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 190,040 and was likely granted around 1875.

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