Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183998, here are decompositions:

19 + 183979 = 183998
79 + 183919 = 183998
127 + 183871 = 183998
307 + 183691 = 183998
337 + 183661 = 183998
421 + 183577 = 183998
487 + 183511 = 183998
499 + 183499 = 183998

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 183,998 and was likely granted around 1875.

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